I went to the ranch today to reinstall the magneto on my 1949 farmall H.
If you have been seeing by posts, The main thing I found was the rotor and drive gear were out of time.
I set them where there suppose to be for a right rotating magneto.
I bring number one piston to TDC, Look at the engine gear that drives the mag,
The pig ears are at 3 and 9 clock hand position. Were they are suppose to be.
I make sure the mag just fired #1 and the pig ears on it are at 3 and 9 also...
I install the mag, then rotate it all the way towards the engine.
I turn the engine over and bring it back to TDC on #1 piston.
I rotate the mag away from the engine towards me, I rotate it all the way out
till I run out of adjustment and the mag will not snap to fire number on cylinder.
If I leave the mag all the way pull out and rotate the engine on it's normal rotation
I have to rotate it another 1.5 inches and it will fire #1...
Makes no sense... #1 piston is on TDC (The piston is all the way up) and the TDC mark
on the pulley is dead on the pointer.
The piston is where it's suppose to be, The mark on the pully is were it's suppose to be, and
the mag drive gear is where it's suppose to be, and I installed the mag making sure it just
fired #1.
What the heck am I missing... I can't see why the mag will not fire #1 when I pull out
towards me on the second go round...
Here is a picture to help you see what I am talking about, it's pretty well self explanitory...
