Hey I have 2 questions. What does sea foam do? And should I use it? And is marvel mystery oil good?
Sea foam is a engine cleaner/treatment to losen carbon deposits & sludge build up.
Marvel oil is a thin, high detergent oil that is benificial to valve guides in 4-strokes.
I seriously doubt sea foam will be much use in a 2-stroke for anything other than a storage treatment. (a fogging oil specific for the pourpous would be better) its to easy to remove any carbon build up on a simple top end job. I do like & use marvel mystery oil as an assembly lube on a motor re-build (its very good at fighting corosian). As an addidtive in gasoline, I again doubt any real benifit to a 2-stroke bicycle motor if your mixing properly already.
