Wico Magneto Timing Marks 

What if you have the 35 degree cup? I have a couple of cups with no number or markings at all how do I tell what they are?

I have been playing with different run timing degrees. I have been manipulating the impulse to start at the correct time(impulse mark on flywheel and case side) yet run timing is set at 15* advance. Do you have any opinions or experience with what I am doing. Tractor is stock just trying for a few more feet at the tractor pulls.

My wico C for my model b unstyled has a long lug drive cup no marks on it at all but has 30 degrees stamped up on top of the marks is that a 35 degree cup I just want to set the impulse lag right thank you

I’ve looked over this video with the one I have and I still can’t get it. By chance could you help if I gave you a part number?

Thanks for the vid, I wish you had a point stick or something lol. All good 👍 appreciated

But how did the onions turn out??

I have a Wico x with drive cup 2061b what degree cup is it?

Is that XH. Magneto

I am working on a 1951 John Deere R I am not sure where to set the timing on the impulse side for the magneto.. Anyone able to give me a hand?

That sorta made since lol, when you turn that over should it make a clicking sound?

So where do I need to be set on my wico x magneto for my distalete john deere A assuming I have the correct drive cup/original magneto
