Unless the thing has stuck rings i cant see much happening though it may do more good with a couple of oz in the fuel.
Trav, how would Kreen do as a Piston Soak in a small lawn mower engine, I was thinking of taking off the spark plug and pouring in a teaspoon of the Kreen and then pull the cord a few times.
I have done this with MMO, just thinking Kreen might give some better results in cleaning things up in the Combustion Chamber.
I bet it would work fine PFan. I'd suggest using more than a teaspoon, a tablespoon would be better. Let sit, pull the cord and do it again a few times over a 24 hour period. Fire it up, warm it up and change the oil. Just make sure the cylinder isn't full of Kreen when you put the plug in and fire it up.
I use MMO as a fogging oil for my snow blower, and once the engine cools I put some in the cylinder pull the cord a few times and it sits that way till spring. The piston top is always clean.
