latest troubleshooting of this problem... and thoughts... Was timing the engine and found the timing inconsistent and occasional no spark. Ohmed out the ignitor and found it to be above the spec'd range of 140-180 ohms... Mine measures 230 ohms... Is this high enough to cause this problem? 2nd... My Northwest Offroad header has the O2 bung coming off of the #2 cylinder. Since the sensor sees only 1 cylinder, could that also be causing the miss?
