Are you SURE your on TDC #1 COMPRESSION stroke? Pull #1 plug and rotate the motor till you feel the compression building, roll it up to 36 degrees. Make sure magnets line up. Make sure rotor and #1 plug tower on the cap line up. That's all there is to it.

dont know anthing bout a crank trigger setup, but from the way your talking it sounds like i needs more timing. have you checked to make sure TDC on the balancer lines up with TDC on the #1 piston? Chris.
