Start by cleaning all parts, especialy the carburetor, and check the condensator. New spark plug can't hurt either. It could be that the fuelcarter oilrings are leaking. 20 second runs are usualy due to that or the condensator. > Someone once told me that Puch made less than 100 of the oil-inject models - > is that true? Wouldn't know, but it seems highly improbable to me. > Also, for the person awhile back who asked for ideas on legally speeding > their moped up - in California at least (we're talking 20 years ago), the law > regarding what was a moped was based on the engine only (50cc or less), which > in effect limited the speed to 30mph. I was able to average 35mph by putting > on slightly larger tires. The 50 cc doesn't limit the speed to 30 mph. It's the way the fuel is lead to and from it. And ofcourse the way all parts function together. My puch for instance has it's original settings but does 35 mph anyway. My honda c 50 does 41 mph. And getting everything optimized will result in higher speeds. A friend of mine has a hobby in classic racing in the 50cc range. His Jamathi minarelli with moto morini engine does 109 mph (174 kph) and with the new gearbox he's working on it'll do over 125 mph. My point, 50 cc wont limit the speed. Robbert
