Spark and fuel, won't run?

[truth609]

Hey all, just put my ski together, jm760 61x. Primed the carb on first start up and it fired right up and ran clean. A week later I install a tank, prime carb and it won't fire. Fires for a second as you let off the start button every few times. I unplug the stop switch, doesn't change. I ohm the pulse coil and reads 15.2. So I replaced the msd enhancer. Install the new msd and still won't fire. Pull the plugs, they're sparking, spray ether in the plug holes and it won't start. As it is turning over for a bit with no start, it kind of "kicks back" and then keeps turning over. Any thoughts? Im very frustrated. Thanks

This is a brand new enhancer from jm. I can't imagine my original one and this new one are bad. I pulled the flywheel cover and the flywheel was not loose as far as grabbing it and trying to move it, but I wil recheck that.

I have had spark plugs that showed spark but when I replaced them it fixed the problem anyway. Cheap test.

It was the flywheel key. Thanks

Swap the white wires, you may need to make a jumper, I had this happen before. Also, check the wires where they come through the rubber grommet going into the ebox.

The flywheel key was the problem.

That will do it also.

check pulser coil wire (white with red stripe.) when it is disconnected skis don't start but rumble as you let go of the green button.
