OK, I have a very confounding cub ignition problem. I’m working on a Cub that I have never heard run. When I crank it, it sputters but nothing will not start. In diagnosing the issue, the timing is way off, the points seem to be opening exactly when they should be closing so the spark is very late.. The tractor has a magneto type of distributor on it but an external coil has been added. I’m thinking that one of two things is wrong. Either you can not convert from magneto to coil just by unhooking the magneto from the points and installing a switch tot eh battery, wiring it to the coil, and then wiring the coil to the points. This would suggest that while coil ignition fires when the points open, magneto ignition fires when the points close.
The other possibility I have in mind is that the magneto drive is somehow not correctly installed. Right now, with the distributor/magneto off the tractor and #1 cylinder set at TDC, the magneto drives lugsslots point exactly up and down.
