Is de-carbonizing a 2 stroke outboard considered periodic maintenance?

[Dave Strong]

Everyone that has trouble with build up is because they cheep out on oil or motor runs like crap to start with . 1964 50 horse 2. Stroke ran every year till 1988 when the rings finally gave up . Motor was never touched other then carbs cleaned , All ways ran wide open And spotless when we pulled the heads .Same thing with snowmobiles . Run for hours and hours wide open never an issue and never had snake oil in em to gum crap up... People that dump tons of crap in the motors trying to make them run better is what keeps the snake oil company's rich ... ... Now flame away ...

Running wide open all the time you wont get a carbon build up, but back to the real world and how many run wide open all day long? A good wide open run after idling through a 1 mile or more no wake zone and having to come back through it at the end of day is not going to get rid of all the carbon no matter what oil you burn.
So is Decarboning a bad thing?? Wouldn't think so.

Do you decarb Ur sleds Dave ? I treat my boat motor the same way I do any other motor I own. Good gas , and the oil the manufacturing company recommends . The best part is none of my stuff loads up and if it did I would fix it . I have seen car motors gummed up with only 50k but the was the owners fault. How many de carb there chain saws?

I do run Carbon Guard in the sled first run of the year, but lucky if I get whole year out of it before I try something stupid. Way less money to experiment with the sled than the boat, its only got 2 pistons to replace and 2 cyl to re Nic.
Have a long way to go between the boat launch and the lake, long slow idle so for me I like to do the de-carbon thing. If I could put it in and drive it probably wouldn't worry about so much.

Do you decarb your chain saw. Good grief, yep, right after the weed wacker and just before the edger. Come on now, apples to apples.

Both two stokes and nothing gets beat more then a chain saw. Not trying to pick on you guys but 2 strokes are ment to be run, just like the 2 stroke Detroit diesels . If ya want to idle all day maybe it's time to buy that 4 stroke Honda

Dumping all kinds of crap in Ur gas tank with a motor that runs on the ragged edge you are taking a chance of changing Ur octane rating and I will put money on it that you are not increasing it .

[Mr. Demeanor]

Just realize that many of these products contain alcohol (like SeaFoam) so if your runnong E10 your adding even more alcohol to the mix. I have found the only thing good about ethanol fuel is I no longer need to run any cleaning/decarbing additives.

[Mr. Demeanor]

If you REALLY want to clean your combustion chambers, bump up the idle and mist some water into the intake with a spray bottle. Nothing works better or safer.

Fair weather boy, yes I do run it my chain saw's but I do run my saw's hard, 4-5 months of the year its below freezing here and I use wood heat so I bet in the last 2 years I have put more hours on a chain saw than you will put on one in your lifetime.

Not to hy-jack the thread-Dave I bet you would like my Echo 2cyl , 69cc,twin carb and exhaust,24" saw! They only made a few about 25yrs ago when the Japs made them before the Chinese took over. It loves the BIG hardwood! Never had carbon problems -- Its only seen Klotz. Gary

Don't necessarily blame "cheap" oil. A lot of people like to associate $$ with quality on oil, but Walmart Super Tech is $12.94/gallon and is one of the cleanest oils there is. Merc Premium Plus is three times the money and about three times messier.

I know a reputable engine tech who swears by adding a little ATF to the fuel in ALL engines. I put half a quart in my diesel truck on every fill up and also add a little to the fuel in the boats and cars. It acts as lube for the fuel pump/injectors and has detergents in it that help clean as you run. It is also CHEEP and sold everywhere!!!! Makes sense to me......

Yes sir

Dave

By the way, I live in the "sunshine" state. We don't usually need heat at all, so I'm sure you do put more hours on your saw than I ever will put on one. So, what's your point, boy. If you've got an axe to grind maybe you pm me or give me a call.

I always used Mercs Power Tune till I went EFI.Just try and hit all 6 on a horn or XRI with the straw. Run a strong dose in a small 2 1/2 gallon tank with OMC's Carbon Guard after motor is warm pull the plugs and a good shot of power tune in all cyl after pulling the plugs and blow the crap out next day. BTW it's good to use an old set of spark plugs for the de-carbon then put the regular ones in after the smokey run.
Lately have made a habit of using Carbon Guard on every tank "got a case of it" can read the numbers on my piston tops after many hours of use.

Dave

Sounds like a plan! Thanks for the tip. Fixing to have a couple EFI motors running.

I do, along with my brush trimmer and leaf blower. BTW my leaf blower is over 17 yrs old and still runs like a top. Decarb has been working for me for years, why stop now?
