seafoam

Would I need to change my sparkplugs after using seafoam? I just changed them and would like to claen the engine out. Also, should I dump it into the carb or suck it out of the bottle through the intake vacuum?
 
Dump it in the carb and check your plugs afterward. You shouldn't need to change 'em but if your gonna clean your engine spark plugs are a cheap replacement.
 
Don't suck it out of the bottle with a vacuum hose. Pour it down the carb, or down the brake booster vacuum line, if available.
 
That stuff seems to actually work. How about some in the tank?
