Decarboning

[awthacker]

These hackers have been relentless lately. This thread is 7 yrs old!!! Funny part is that the question was never answered (suprised Mac_Attack stuck around after that!). BUMP!

I decarb with seafoam. With my the 115HP on my old boat, it seemed to help alot after the 1st treatment. Cleaned the cylinders and plugs up good. Gotta think it cleaned the carbs some, too. I mixed it as recommended with fuel/oil mix in a pony tank. Ran it on the hose with the pony tank for awhile, then fogged the air intakes with Deep Creep until eventually bogging it down. Then let it sit for 30 mins and restart on the hose and let it idle. The nastiest white smoke for awhile, then the engine just seemed to start purring. I didn't notice much improvement when I did it to the Intruder, but I'll probably do it a couple times a year.
