Bike is new to me, did not run when purchased in several baskets. Put new rings, points, condenser, coil, spark plug, rebuilt carb, new brushes on generator, new clutch plates. Points gapped @ .020 plug gapped at .025.
Motor starts on first or second kick, will run for maybe 30 seconds. Carb is getting gas but engine does not respond to the throttle ( it does not increase in RPMs as the throttle opens ) the throttle is functioning properly. If it is possible for a 2 cycle motor to backfire, this one sounds like it backfires.
At times it runs long enough to drive a couple of blocks, but has no power or throttle response. New gas and proper oil mixture. Have let gas cap off suspecting venting issue with no change. I can't readily identify the timing marks on the breaker plate or crank, will check that out.
