My Farmall H won't run. The problem started with my removing the magneto drive to replace the gasket. I ended up loosing the timing marks on the Magneto drive. I was able (By LOTS of trial and error)to get the magneto drive to where I think it belongs. The magneto clicks before the #1 terminal on the distriburor cap when the #1 cylinder is at TDC and the pully is at the first mark. My problem is that my Farmall H now won't run. We even put some gas in the cylinders, no luck so we think it must be spark. I dressed the points, replaced the cap and roter. I think it has a good spark then a weak spark, I am not sure if it is inside of the cap orin the magneto itself. It was hard for me to tell. It was necessary for me to trip the magneto a lot( Not hooked up, maybe 30 complete revolutions) so I could figure out timing it. Could I have messed it up? Also, the kill switch screw turned while hooking the wire back up, could this be the problem? Thanks!!

I don't hear you say that you raised the number one cylinder to compression stroke before you put the mag in and set it to number one.
Did you?

Make sure that you didn't install the magneto 180 degrees out. It's easy to do. Just be sure that the piston is on its compression stroke when the timing mark is at the pointer. Hope this helps, Bob

Thanks!! The magneto clicks when #1 cylinder is TDC on the compression stroke at the first notch of the pulley.

Hi John, NO you did not mess it up. Take the coil wire out of the dist cap and hold the electrode abou 1/4" away from the screw on the side and turn it over and see what you have. If nothing try unhooking the wire to the screw on the side see if its the push pull switch. Let me know what happens along with the color of the spark if it has it. and we will go from there.

Thanks!!! I put the coil wire 1/4" from the magneto side screw and turned the engine over by hand. I checked the push/pull switch, it appeared to work ok. I got a spark every time but the spark looked sometimes orange, sometimes blue .
