I take back what I said. I dont personally know much about Labnerd Cept he knows his **** on oil because he does something with it for a living.

Please follow labnerds advice and dont put ATF into your motor.

 

ATF in crankcase = BAD.

Got it

 

nevermind, dont put ATF in the crankcase

 

As mentioned before Auto-Rx is a great product for cleaning internals including valve train and piston ring packs.....the valves with carbon build-up will require a specialized cleaner or water injection which basically steams the carbon right off. Ever put water in a very hot, baked-on frying pan?

 

Not sure about vehicles but Seafoam is definitely not snake oil for unplugging small idle jets and sticking float needles in motorcycles. Always the first thing I try that works about 90% of the time. If the carb is too mucked up I pull it and clean it. Sure saves a lot time when it works, though.
