said by alkizmo:As I mentionned before, try to run PURE seafoam through the engine, even if it won't keep running, force it. It will make a ton of smoke! but it will clean whatever is along the way.
I'd be more inclined to try this if I hadn't been using Sea Foam all along. I'm obviously not an expert on combustion engines, but after the constant Sea Foam additive and then the concentrated shower of carb cleaner, it seems unlikely to me that carburetor gunk is still a possible cause. Are you sure that burning pure Sea Foam isn't bad for the engine?
