weird cutting out problem

schwinger said
ok when it stumbled and didnt want to start i checked down the carb and it was getting fuel, thru the accelerator nozzle. Took awhile to start back up but finnaly did and it started up crappy tho but smoothed out and was able to go on my way. ran smooth for 30 minutes and started cutting out when i throttled it more. ran smooth intermittently but when i got off the off ramp it died at the stop. took awhile to start up again but did and i just limped it back home. The coil is an accel 40k volt and its somewhat old. The ignition box is sharing with the ballast resistor also. This problem is driving me F*&^*&%^&%^&&^ crazy!

I'm not recommending buying a new coil, however if you have another one laying around try it. Take it for a drive and see if your problem still exists. Another possibility is the pick up coil in the dizzy is going south.

Anytime I have experienced this it is quite random. You might drive ten miles and it quits or you might drive 50 or 100 and it quits.

It could be gas related too, but the way you describe it makes me lean towards coil or pick up coil, they get hot and cut out, cool down and fire up until they overload again.

Anyway it's something else to consider, keep us posted.
