another dis-satisfying boating weekend...

[cocacola]

When premixing fuel and oil, which is the recommended method: Add fuel to tank, then add oil or the opposite. For me, I add fuel first to accurately add the right about of oil. The reason I ask is that yesterday, my engine fired pretty quickly….then it quit and wouldn’t run. Many failed attempts, plus flooding and I was pissed. In the parking lot, I disconnect fuel line and turned on the pump. The fuel looked like maple syrup. It was like the tank pickup grabbed all the oil and no fuel. I drained the bowls and kept pumping until consistency looked good. Hours later and still pissed, I tried to start again and it did. Unfortunately, I did not have a plug wrench at the lake with me to clean/replace oil soaked plugs. We ran it fine for hours.

On another carb note, I am frustrated. I use to have 46 idle jets and 72 high speeds and no back drafts on my WH20’s with enrichment solenoid. How is the spring loaded screw supposed to be adjusted? Do you need to adjust enrichment solenoid? Anyway, my boat came with a 2.4 Offshore 245hp engine. A fishing 2.5 was put in it’s place when 2.4 was worn out. Many parts appear to be transferred from the 2.4 to the 2.5 and I suspect the carbs. Are these carbs suitable for this engine (especially since we ski)? I have rough unstable idle. My starting battery is weak and needs to be replaced, but I don’t think that has anything to do with idle and low speed quality…or could it? It’s like the engine is running really rich on low end. Jets are now 60 idle and 78 high speed. I took them apart, changed seats and needles, set float levels and reinstalled. Little changes has occurred. Need to recheck timing again...

going to prop down to 19" HighFive for skiing too and get rid of 22"

You need to have a little agitation to mix the oil and gas. Usually, the best way is to put the oil in first, then the gas. If you dump it in last, it goes to the bottom and lays there till it gets agitated somehow. On a big tank, it's a good idea to mix your oil with a few gallons of gas in a seperate can, then add it to the main tank, then add gas.

That's another reason I have decided to stick with the auto-oiler. If you're worried about failure, just add about an ounce of oil per gallon to your main tank to keep it alive till you shut down after the alarm goes off.

You'll like the high five for skiing, and so will the skiiers.

You hit the nail on the head with oil mixing. I pour 32oz of oil in last and that's probably what happened to me. I'll try your suggestion(s).

Now if I could just sell my existing prop to help pay for the HighFive.

oil in first then gas then drive stop and go traffic to mix till the landing.but it does not work if the tank is really full cause you need slosh.pour oil with gas when you fill for the first couple of gal.

one thing I have not looked at is my reeds. No matter how this thing is adjusted, it seems idle quality stinks (and holeshot too). I can tell it has Boyeson reeds (reed within a reed?). Small one looks black and larger is tan or something like that. Maybe they leak. High speed running seems fine....but it's sluggish off the line. Considering some of the other cluster%$#@ stuff I have delbt with, it would not surprise me to find trouble there. You should have hear JSRE on the phone when he saw my heads and the fact the alignment pins weren't in the block.

From here on out, I will mix fuel like I have always done. Heck, I had an hour drive after filling up. Why I didn't oil it at the time.... I don't know. Never did that before.

Kind of hard to pour the oil in first if you're topping off the tank and don't know how many gallons it's going to take??

If the tank is empty I agree. Shooting a stream of gas on to the oil in the bottom of the tank isn't a bad idea.

If you have old gas in the tank I could understand your problems. Some of the gas can evaporate and leave a oil rich mixture. Plus, todays gas doesn't seem to last too long before it goes bad and when it's mixed with oil it goes bad even faster.

Opinions based on personal experience not science. YMMV ???

ALWAYS OIL FIRST if your topping do a 2 gallon mix at a time...

what i do is oil in 6 gallon intervals... that way im either dead nuts 40:1 or richer depending on fuel added i have a 24 gallon tank and a measuring jug for oil marked at 2, 6,10 gal...
