Magneto timing

Recommended Posts

Hello,

 I am working on a 1913 Jackson. It has a replacement American Bosch magneto with a impulse starter.

Does the impulse need to be "pre loaded" to time the magneto? 

Does anybody have any published material how this is typically done?

I have a Dykes that says to preload and set retarded on TDC. An old tractor manual says to preload and set 5 degrees ATC.

I have tried both as well as no preload TDC.

I hate to use my last Toyota repair kit on this car. (1/2 stick TNT).

Any ideas or help?

Thanks,

Dennis

Layden,

This may be exactly what I need .

I considered setting it up backward ( reverse rotation) but I convinced myself this couldn't 

possibly be correct.

Thanks a bunch.

I'll let you know the results.

Thanks again to Layden and the forum.

Following up as promised.

Set it up backwards per the manual.

Two pulls cold ( one choke) and first pull warm every time.

Schebler model O still a little rich.

We're getting closer.
