61x electronics with MSD CDI. I've read the FAQ section on troubleshooting. "Spark as I let off start button" syndrome. Seems to me it did that or at least I had spark but only once, can't remember for sure but I was checking for spark before I read that part. It states it can only be two things, actually three. Bad CDI, Pulser coil or wire connecting to it to E-Box bad. My problem is this: If the motor cools down ie: CDI, Stator and ign coil the spark is back and motor runs. On other motors with a mag I've always known this to be a bad stator. Or in this case maybe just the Pulser coil. I've already switched back to OEM CDI box and getting ready to check Pulser coil voltage. Anyone help narrow this one down before I dump it in the water and swim back to shore.
