Thanks for posting this. I put off installing the mag for 2 years after getting frustrated.. I came across your video and got to it. Perfect instructions. She's running nicely now. My 1942 is back in action.
@@JPN76 The source of confusion was the CEN and the FIRE marking. I think I was trying to time it to the wrong mark.. Your video was exactly what I needed.
Compliments on the production quality. Great lighting and focus. I inherited a1948 Allis Chalmers C that had been 'converted' to a coil ignition by modifying the mag. Difficult to start, kicked back hand cranking. Put a quality rebuilt Fairbanks Morse mag on it and discovered I cannot tilt the mag over far enough to time it properly. The conclusion can only be the mag drive gear teeth are not aligned properly on the machined marks under the front engine cover! I better not find paperwork from the engine rebuilder. Your video clinches it. It is not possible to mount the flywheel incorrectly to change the location of the timing marks, Allis Chalmers made sure of that.
Very good video! Very well explain. Is it possible to use a timing light with a crank start. The last person who worked on our tractor broke his wrist because the crank kicking back. I liked the idea of you using a modified ratchet wrench. Why I didn’t I think of that?
I noticed, you don'''t have a 'boot' on your plug wires. I have seen number 4, have the spark jump to the oil filter making the engine miss. Probably more likely to happen if you plug is slightly fouled, but it is something to keep in mind if a random miss does show up.
It showed up in my video with my dad driving the tractor. I don't remeber it being that close back then. Maybe oil filter was a tad shorter or something. Or my memory is a tad shorter.......
@@JPN76 Ok......I got good spark with the first cap on.......Using a screw driver in the hole, but when i put the outer cap on w the 4 plug wires i dont have any spark at all??
Another way to do it is ignore the marks turn slow until you feel compression pressure on the cylinder #1. Then slowly turn until the notch/slot on the governor shaft that the Mag fits Innis horizontal. Set the Mag to #1 and bolt it down. This should work. I plan on another vidnof this at some point.
Very good video, and information, Thank You much.
@@kenlutz5243 thanks you are welcome
This video helped me immensely

thanks for posting
Glad I could help!

Thank you for your very informative videos! I wish I would have seen this one a couple months ago when I was firing up my IB after a 16 year rest!

Thanks for the feedback. I agree with you about the mag timing. Does sound like the governor gear is not timed correctly.
Very well done. I learned something. I never knew you could wind the magneto backwards.
Thanks
Nice info! It is nice that you actually show it as well as explain it.
Thanks
Great explanation. Thanks for sharing
Thanks and you're welcome
Great video.
Thanks
great one- Professor..

Yeah you can use a timing light. Younwont see the TDC mark, but the Fire mark instead. If timed too early it will kick back on you for sure.
@@JPN76 Thanks for the reply. I’m going to try and find someone to use a timing light on mine. You’ve been very helpful.

I think the old original filters with the rolled seams and flat tops, were a bit shorter than the currently available filters.
I am repairing a mag for another guy...."B" I took of the lower cap......do I need to time it( the rotor) to the gear on the Mag.........?? Clayton
@claytona8962 if you have a FMJ mag then yes. Mine is a FMX so i didnt have this step.

@claytona8962 look at this video around the 20 minute mark. th-cam.com/video/K-7vlWzzlI0/w-d-xo.htmlsi=8CY8T9rIzBwIHpil
Hello, need your help, my Allis only has 2 points °° no Fire and Cent brand, how do I have to set it? thanks and greetings from Switzerland
