Trouble starting in start position, points set too wide?

[ronboonville]

My martin only starts when mag is almost fully advanced. Is it possible I have the points set to wide? It is hard to tell what is fully open when setting gap.

What mopdel Martin?
Check the gap .020 on highest point of cam.Plugs gapped at .035. If the cam is removeable is it installed right?
Does the stator plate cam pick up the carb at the correct point.
Is the stator plate stable,no wobble or is it bent?

Thanks for the reply, it's a 45. It's hard for me to tell where the highest point is, think it is about where the flywheel key is. points at .020, plugs .032. cam is right or I think it wouldn't run so good after it starts. Not sure about the stator plate cam, I have it set about half way out. stator plate stable not bent. I may just need new plugs gapped right the old ones are ac 44 and a basic points education. Does narrowing the gap make it fire sooner? like it was advanced?

It will advance the timing sort of.It also will change the relation of the points to the peak time of the relation to the magnet in the flywheel.I don't have any tech info about the Martin But if you set the points and observe their action as you rotate the crank you should be able to the highest point.
As far as the stator cam there should be some sort of indication of where it should just pick up the carb.
There probably is a stop the limits the advance of the stator timing as you operate it.
Another thing that could create problems if is the flywheel key is sheared.
If the flywheel nut wasn't torqued enough the key could partially shear.
I don't think it would require you to advance the stator, it would just mess up the magnet,point relationship.
