How do I set gap on my cub

Listen to George, he knows what he is talking about, and he really is a Cub Guru.

If you want to do some reading and learn more about your Cub, visit the Cub Manual server at the link below. Read the Owner's Manual and then check out the Blue Ribbon Service Manuals. Really good stuff! Also, check out the Best of H.L. Chauvin!

The gap should be set at the HIGH side of the cam (what I assume your are calling the arbiture). That means on one of the four corners, not the flat side. That is probably your problem. Otherwise, I would suspect timing. But I would re-gap at "high cam" right now, and try that out. If that doesn't work, be sure to check back here. Good luck and don't give up! Glad to have you on this board!

The amount of the gap depends on whether you have a distributor or a magneto. In either case, the gap is measured between the point contacts themselves. It is done with the cam follower resting on the high part of the cam lobe. For a distributor, the gap should be .020", and for a magneto it should be .013". Make absolutely sure the points are CLEAN! The last thing will be to draw a piece of clean paper between the points to make sure.

Good luck getting it running. We'll try to help.
