Pe Reivers
I enjoyed reading your post on the oil,s job in a engine. I started doing what I read on a 2 cycle oil can about 25 years ago. I read it was good to at the end of day, to rev up the engine and flood it out. I first did this with a chainsaw. I was skeptical about fouling plugs at first. It did not fowl plugs, but I noticed the engine started far better the next time. sometimes with no choke needed. Then I tried it with my 338cc snowmobile that had a Yamaha Twin. I would have the sled on a stand where I could rev up the engine and clear all snow off the track. I then would place fullthrottle & fullchoke and flood out the engine. The next day it would also start with no choke needed. It was then I noticed that on start-up I could see a lot off loose carbon blow out of the exhaust onto the white snow. Well I never fowled any plugs in that engine either. In fact it was the fastest stock sled exactly like it in the area.

Now 25 years later I sold the saw real cheap to my son-in -law. He runs it just like I did flooding it out. This saw never needed a carb kit or any major work at all. Maybe 2-3 spark plugs & a pickup hose in the fuel tank. You may have seen, the by now famous pile of wood my son-in-law cut with this same saw in 3 part-time days.

I believe the flooding out soaks any hard carbon forming...and on start-up the loose carbon leaves the engine.I never took head off to de-carbonize it. What is your response to this? Thanks Capt,n
