It really sounds like fuel..Are you sure you rebuilt the carb correctly? Gasked in the wrong order or the metering spring bend under the arm (instread on locates in the nipple).


There is no electrical diagram... It's just a simple magneto points based system. The switch just shorts the points to ground.

If it has "erratic firing", your points may need to be regaped or the condensor is bad.
