How I spent my Saturday afternoon

[Mr. Demeanor]

Thanks for taking the video Mike (Dago). I am always the one taking the video and have very little of my boat running. I really dont know what it looks like at speed.

Starting to lean on the new motor more. This is my small cruising prop at 7000-7200rpm and low 80's. Still very rich but have some carb mods coming so I havent spent much time on them.

Pulled a head when I got home and it looks pretty rich...sounds it to according to Mike. Hard to tell when your driving.

Electric truck Mike and Karl built. Mike can give details. I know nothin....

Leave it alone !!!! You'll smoke it !!

[Capt.Insane-o]

Leave it alone !!!! You'll smoke it !!

Yeeeaa.. I'd clean the piston tops and the next session do not idle it more than it takes to get away from the trailer and on plane.. run a tank of fuel through it and peak again. It appears to be on each of the rich/lean spectrum.

[rkmirage]

It looks good aired out. Thanks for the video, I've always wanted to see what it looked like from the back, my usual view is looking back over my right shoulder!:p

[dagodiver]

That boat sounds fantastic.! Hauls the mail pretty good also.

Dago

[Mr. Demeanor]

Leave it alone !!!! You'll smoke it !!

so what you saying is I should remove the airbox right :leaving:
how else am I going to keep up with all you fast guys???

[Mr. Demeanor]

Oh and I never idle. Wide open, click it off and coast right up on the trailer. Went through a few boats and tow rigs before I got the hang of it but Im pretty good now. If anyone ever needs help at the ramp loading their boat, Im your guy!

[fastcat]

Sweet. Thanks for postin

Its true. Its on the interweb!

[MotoAce]

Cool video. Wish my 3cyl ran that fast!

[Trent Ashby]

That's really cool, bet that little boat hurts lots of feelings.

Its a PWC killer. Attracts them like a magnet.

[rkmirage]

Is 89 still your top #?

[Da Bull]

That little Biel tunnel runs like a bigger boat. I didn`t hear any four strokin. Remember, It takes fuel to make hp.

DB

[Mr. Demeanor]

Is 89 still your top #?

Yes. I havent had a chance to try and really string it out. I had the 28 pitch on it today. Lots of oil still but weaning it off. No real point until the carbs are done which is happening Monday it looks like.
I will be down at the lake sometime this week dialing things in before heading to jasper.

[Dave Strong]

Sounds great for a 4cyl, seems to run real strong. Don't get in a hurry to lean it and squeek it you got way to much into it to stick a piston.

Dave

[Capt.Insane-o]

Lean is not mean.Gas is by far cheaper than parts, and it sounds and looks killer.

[Mr. Demeanor]

I am being pretty careful. Actually a lot more careful than anyone I have known breaking in a motor but there are a lot of unknowns with this build. No plan to follow like most of you guys have. I am slowly weaning off the extra oil and av gas mix and just keeping an eye on things. Today was he hardest I have run it and when I got home I checked compression, leakdown, and then just decided to take a look. There really was no point in doing much with the carbs other than keeping it rich until I got them bored which Dago is doing now. Even though it looks really safe where it is, I will go up at least one more drill size after there bored and see how it looks. Im taking it to Jasper and would rather have it fat and happy for the fun run.

[Mr. Demeanor]

I still cant believe its taking .092 jets and not just stupid rich and 4 stroking.
Bottom plug is after todays shenanigans. Looks nice and clean for huge jets and 30:1. Its sucking fuel at an alarming rate for only have 4 cylinders!
Its getting there and I am getting a feel for it at higher speeds. Definitely less trim needed.

284607

[Capt.Insane-o]

Bottom plug looks fine. Yepper it's gonna need some fuel. You are going to have a blast on the river run.

[Mr. Demeanor]

Yup, I pretty stoked. Been talking about doing it for a few years.

Ps. If you havent yet, go see the movie "Rush".


One other thing made me curious. On the top plug in the pic, even though its dark and has carbon chunks, it also has a perfectly clean shiny metal ring inside next to the ceramic. I have never seen a plug do that. Its a small beveled "step" in the metal. It actually scared me when I first saw it as I thought it was aluminum.

[timmc6]

Friday temp for jasper is gonna be about 75 low humidity, gonna be nice!!!!! Tim

[Capt.Insane-o]

We went opening night to Rush.. excellent, on par with Grand Prix.

If the motor does not need Av gas don't use it. Back the timing off if you are concerned and use your normal fuel and oil mix and creep up on the tune. Before you go ****ing around with carbs put a few hours underneath it.

[Tom Foley]

Have fun Timmy and keep your eye on this lil tunnel ! Mr Demeanor , oil is power don't go too lean on oil , I'm sure it's helping your crank . I'll bet you won't gain any power by taking away oil .

[tux974]

That looks to have been a terrible afternoon for you ;):D Sounds and looks like it is running very well :thumbsup: While in breaking...slow and they go fast and it may not last :nonod:

[XstreamVking]

Nice running attitude. Very impressive little boat. Keep on tweaking it, 90 can't be that far away.

Just remember the more fuel the more HP, was once told it takes about a gal/hr for every 10HP.

get a merc that's all lol

[dagodiver]

Fun ride for sure.! Thanks for the video.!

Yes in a perfect world you can make 12hp for 1 hour with 1 gallon of gas.
18hp for 1 hour with 1 gallon of diesel fuel.

Dago

[Mr. Demeanor]

Merc 225 Promax on my boat = 95mph. Im going to be pretty damn close.
Greg Scott is supposed to be putting a 300 Drag on one. I'd drive it!

[Superbender]

Very cool

[Capt.Insane-o]

It sounds great when the pedal is put down. :) There is/was a fuel dock just west a few hundred yards of the downtown dock in Chattanooga on the south side. It was a DIY card swipe pump with 89 oct.

[Tom Foley]

Greg Scott is supposed to be putting a 300 Drag on one. I'd drive it!+
:eek::eek::eek:

[rkmirage]

With the same setup, the Promax would be wayyyyy more than 5-6 mph difference over that Yammi. 75 more propshaft H.P.........

[rkmirage]

Having said that, I think the balance would be off with with another 65 lbs on it.

[dagodiver]

Hp is not always the answer. He has a major balance issue
To deal with. He is going about it the correct way. He has
A few ideas on how to get more weight off of that motor.
My boat is a perfect example of hp isnt everything.
I would be surprised if my motor was even putting out 200hp.
I spun it faster saturday than i ever have and that was with the big
Prop. Mr. D's boat was performing very well all day at all speeds.

Dago

[Mr. Demeanor]

Having said that, I think the balance would be off with with another 65 lbs on it.

Yes Rick and that is the issue. I am sure the 225 boat would pull me on acceleration but how driveable is it and how is that extra weight effecting the overall performance. You have to remember this is a 13' boat with a 4" notch at the back of the sponsons. I cant speak for his setup as I dont know. It may be way off. I have two engine height settings. They are 1/2" apart. With it in the lower setting the boat drives very nice, doesnt hop much and if it starts to hop, a little push on the go peddle stops it. With the engine up 1/2" higher, its 3-5mph faster but hops a lot and is real flighty. Because I run on the bottom of the gearcase, raising the engine also increases bow lift by letting the bow come up higher before the gearcase (which is acting like a trim tab) planes the surface of the water. Its all balancing act with this thing and like a teeter totter.

[Mr. Demeanor]

+
:eek::eek::eek:

Yup, my understanding is its a 12" mid 300 drag that weighs less then my 4 cylinder. I hope I get to help him set it up and have offered. The weight being very similar to mine should have a similar setup. The power will be insane and I dont see any way you could use it all.
I am going to do a 15" mid on mine. Been looking for the right clamp/swivel parts and have some ideas.

[baja200merk]

Come up to tarpon thurs night, I'd guess 94.5 with my 15x34 ET :D

[Mr. Demeanor]

Come up to tarpon thurs night, I'd guess 94.5 with my 15x34 ET :D

Ill be in Jasper. Maybe the following week.
I will need a tall prop to pt up that big number. This motor is very torquey. I am pulling my 30ET to almost the same RPM as the 28.

[baja200merk]

Thats great news. Sounds like a big improvement. I will go to jasper again for sure it was a great time. Put the safe tune in it and have fun :cheers:

Chris, Mike, lookin good guys. If i didnt pop my 300xs already i would have been out there!!!

Cylinder or compressor? :eek:

[rkmirage]

You're right, it would be unuseable hp. After I wrote that I thought back to years ago when a friend took a 140 xflow off his Viper, put a 175 on it and while the boat had better accelleration, and maybe 1-2 more on the top, it changed the manners and it was undrivable.
I know you are going about this the right way! 93 is my best # right now, I know I better step up my game. You're not in the house yet, but you're on the porch!!!

[Mr. Demeanor]

Its going to be in that ballpark but will take the right day, right weather etc. My carbs are bored (thanks Dago) and I am picking them up in a little while. The crazy jetting sizes I have gives me good feelings that the bigger carbs will work well.

[baja200merk]

Ran my buddys River racer yesterday 28p went 91 my 34p went 99.7 with motor buried (old wore out 2.4). If you gain that much over your 28 you'd be the fastest biel in the country :D

Bummer. :(

Just putting my carbs back together. Run it tomorrow.

So you just bored the venturie? There's more to be done... I'll try to dig up some pics of what Kottman carbs look like...

Im sure there is. The flwobench guy is going to take a look at the spare I sent over. I just needed to get it back up and running for Jasper.

[Mr. Demeanor]

Heres a thread with pics of his. Not drastically different and his are designed to e used with velocity stacks. Im not a big fan of stacks.

I miss those carbs lol...

[Mr. Demeanor]

Cant tell you how bummed I am that I am not going to make Jasper. Ran the boat a couple days ago and the last pass it started backfiring at idle. I have been chasing it for tow days. Found a loose ground on the ign. box and thought that was is. Then it continued so I pulled the intake and found two rees pushed backwards into the cages (from the backfiring). Thought that was it so in with new reeds and still wont start, wont idle, backfires. Thought timing, trigger, flywheel key, etc. etc. been through the carbs three times.
Well, its 11pm and I finally discovered using soapy water I have an air bleed passage for the idle air jet blocked. No amount of compressed air and solvent seems to be able to clear it.

[baja200merk]

Put stock carbs on it and go! I can get v4 yami carbs tomorrow if u want to borrow them.

[Mr. Demeanor]

Put stock carbs on it and go! I can get v4 yami carbs tomorrow if u want to borrow them.

Its a 10 hour drive. I would have to leave tomorrow early. I injected that passage with chemi-dip and am going to let it soak over night. Theres an outside chance it will eat through whatever is stuck in there. I am not 100% confident that is even it. I just cant get carb cleaner through it and can through the other 3. I dont know how something could get past the jet though and then clog the passage. The jet has to be the smallest part of the passage or its not doing anything.
If its not that, I bet I fried my ignition box with the loose ground wire. It was the ground right off the ignition box. I had not make a custom bracket to mount the ignition and the ground was one of the bolts that held the bracket. It must have vibrated enough to loosen. I have aplace locally that has all the those parts, I am just out of time.
I gotta tell ya, I have NEVER chased my tail like this and did some dumb stuff to boot.
Loose ground, thats it.....nope.
Pulled carbs and checked reeds.....all good.
Bad spark plug....nope.
Link and sync and double check all connections...nope.
Notice bleed line on #1 jump when it backfires out carb....pull intake thinking maybe a chunk of my epoxy came loose.....nope. But now its backfired enough to stuff some reeds.
Off to Pro for reeds.
New reeds in and thinking maybe that it was it....nope.

Heres where I am going to admit to just having my head up my ass. At this point I would have walked away for awile, maybe gone fishing, but I wanted to go to japser so I throw a timing light on it and its 10 degree off at idle cranking. Now maybe the flywheel key broke. Borrow a flywheel puller...nope.
Heres the good part.....
My timing light has a dial on the back to advance/retard and it was turned 10 degrees the whole time. I am going to super glue that fgriggen dial as I never use it and its f'd with me before!
Put it all back together, fire it up, still not right and just for kicks I pull the big brass screw off the top of the car for cylinder #1 and it stops backfiring. The broken reeds were on #1 and #2 which feed off the same carb body so I pulled that apart and here we are.....

And thats how I spent my Tuesday and Wednesday afternoon, evening, morning etc. More overall time than it took to assemble the motor!

I should thank Brad and Don for fielding some phone calls and Brad for lending me his flywheel puller.

[Mr. Demeanor]

Just pumped some more chemi dip through that passage with a syringe and it went right through so who knows....

On a side note, I did run great with the bored carbs. I didnt run the big prop and just worked on tuning but the hole shot was actually better which surprised me. It ran great for a couple hours before this problem started so it wasnt the carb boring that caused it.
That passage in the carb is complicated. It draws fuel from the bowl through the jet in bottom of the float bowl. It draws air through the main air jets. That mixture is then combines with more fuel drawn up from the bowl through another passage and controlled by the mixture screw. I am almost wondering if there is a check ball in there. You cannot pass a fine wire though the main air jet into the area under the big brass cap screw.

[dagodiver]

Sorry.! Yikes.

Dago.

[Mr. Demeanor]

Going to try again in a few minutes and then decide if we are going without the boat.

[baja200merk]

AND!!???

The suspense is killing me!

[rkmirage]

Did this happen after I left the lake? It sounded better with the smaller jets.

[mach351]

You should come regardless if you've got your boat or not....Jasper is always awesome to watch.
