Hello. I recently exchanged my old WICO C I was having some trouble with for a rebuilt WICO C. Now I am trying to install and time it. Can someone let me know if I am doing this correctly?
My first step is to stick a wire into the top plug hole and run it to a place 1/8" or so from the mag frame. I turn the coupler until the impulse snaps and I get a good blue spark.
On the tractor side, I remove the valve cover to watch the valves and watch the LH cylinder intake valve open and close confirming I am now at a compression stroke. I roll the flywheel forward until the LH IMPULSE mark on the flywheel lines up with the line on the tractor frame. At this point, the coupler on the governor is horizontal. I install the magneto and finger tighten the cap screws. I then rotate the magneto forward (towards the front of the tractor) as far as possible.
I now go back to the flywheel and rotate one complete revolution, and again line up the LH IMPLUSE mark on flywheel with the line on the tractor frame. As soon as I get to this point however, the mag impulse trips. I thought the last step was to rotate the mag rearward slowly until the impulse trips? Is something wrong with this procedure? It doesn't seem to want to start following this procedure. New plugs and cables and correct cables running to each cylinder.
