I replaced the point wire 10 or 12 months ago. Points aren't dirty or broken. I just checked spark plug it is a Champion h10c. I gapped it today .025". Set the points with a timing light, S in the window of the blower housing. The carbs high jet screw 2 1/2 off the seat, low speed 1 3/4 off the seat. I have tried 1 1/4 off the seats but it runs worse and a shorter period of time.
