This one is driving me crazy:<br /><br />Electrics appear to be OK. Compression is OK. Rebuilt all 3 carbs using OEM carb rebuilt kits. Replaced CDI on offchance. Changed plugs, swapped coils, etc. Fresh fuel.<br /><br />Problem is #1 cylinder does not fire at low RPM but fires fine at 1500+ RPM. In other words, at idle engine runs on cylinders #2 and #3.<br /><br />Any clues where to go from here?
