Ah, I have even more of an appreciation for this stuff now. After sitting for two weeks waiting for a new battery, the Boreem Robot 50cc scooter (a.k.a. "Rolling Thunder") wouldn't run worth a damn and I was getting pissed, uttering many unrepeatable profanities since I really didn't want to pull the carb out again and clean the jets which is a PITA unless you're blessed with small Asian-sized hands and Asian-type patience, neither of which I possess.
Decided to hit it with a heavy dose of Seafoam and follow my wife's advice of "Maybe it will start in the morning."
I dumped a prodigious amount of Seafoam in the tank and rode it, sputtering and stalling as far as I could to try to move some of it into the lines and carb.
Sure enough, this morning it fired right up and is running good. Since it doesn't use much gas, I think from now on I'll run about a 50/50 gas/Seafoam mixture in the Asian Nightmare. I wonder if it would run on straight Seafoam?...................
