I bought a 4217 cdi and a hall effect trigger. I have everything installed on my K301 Kohler 12HP pulling tractor engine. I cannot get it to fire. I don't think I am getting a trigger signal. I have an aluminum disk on the front (opposite flywheel) of the engine. I sunk 4 magnets into the disk and mounted the hall effect behind it. What is the air gap for the trigger to work? I am at about 3/16" now. I can't get much closer with current setup.

I also have no LED with power to trigger. Once it is disconnected it lights and when I reconnect I get a spark. What am I doing wrong?:confused1:
