My 1978 Puch had no power all winter long, top speed 20 mph, I thought it didn't like the cold, because when it warmed up it seemed to run a little better. But yesterday it was 55 degrees out and top speed was still 20 mph. So my first step was to clean carbuerator. Cleaned carbuerator put it back together, then it ran worse than before. My next step I started draining the gas out of it to clean the gas petcock. Took out petcock and the rest of the gas flowed out with some crap that was inside gas tank. Cleaned petcock, put back together, and now it runs great. I also cleaned the Points using Fred tune up tips, great idea, thanks Fred.
I am thinking about a BI Turbo for my moped, does everybody think that a BITurbo is worthwhile.
