It is a 1951 s125. Got it to start, but will only run about4-5 seconds at most, then dies. Most of the time, runs only 1 or 2 seconds. Checked the petcock, it is junk. I wiggled the wing on it and pressed down on the tickler and got fuel to overflow the bowl. seems to have made it worse. Maybe flooded it??? Of course, I've been playing with the timing also. I think I have a dual problem--gas and timing. looks like I need an oe petcock.

If you have spark & fuel/air being delivered check that the spark is at the right time. keys may shear wholly or partially. Other problems may be that adjustments may have been made correctly by the marks but parts came from other engines. Doug

What are you trying to start? If you have spark then your problem is fuel. The wing-type fuel petcocks are notorius for either not shutting off, or not flowing fuel. If your bike has a Linkert carb all you need to do is press down on the "tickler" rod on top of the float bowl until you see fuel flooding out the top, set the choke, and kick it until it starts. If you have a Tillotson carb it is a lot harder to tell if you have fuel in the carb. More info please on what bike you have.

need help cranking for first time. won't stary. have spark. would anyone care to help me out, give me some things to check, possibly give a phone # to call you/
