Thanks guys !
I've seen that seafoam in action allready and it works ! just by pouring it down the carb.
I don't think I should pour any seafoam in the crankcase oil though because this engine is a sludge bucket inside and it would probally plug all the galleries or oil pump pickup up and creat more problems. afterall it is a detergent and will loosen up all that crud .
I think I will try it down the carb though.put somein the gas tank too.
