timing an allis chalmers C

The service manual isn"t much help in how to time the tractor and reinstall the magneto. What is the proper procedure? There are 2 marks on the flywheel - center and fire - I can view them from the bottom. What does each one mean? If number 1 is at top dead center which mark should the flywheel be on? Thanks

To be able to hang the magneto and not have the impulse spring wound tight you have the FIRE line in the center of the inspection hole on the compression stroke at number one cylinder/plug hole. To check after you have the magneto installed you can crank the engine over slowly and the instant you have spark on number one plug you will have the TDC or CENTER line in the inspection hole. The magneto has to be set up and ready to fire to number one plug when you install it.

So if I have compression stroke on number 1 - I line up the fire mark on flywheel - turn magneto backwards to number 1 - hang the magneto - turn slowly to center - it should fire at that point? Thanks

The hole where you look at the marks is on the left side not the bottom.
