1993 Suzuki King Quad 300 Backfire

[Jodawg1981]

So i got this from my boss. It sat for a long time. I cleaned the carb, had it running for 2 weeks with no issues.then this past saturday it shut off after riding for a while. Tried to start and it went to smoking. Fried the harness. Well thru the week i repaired and rewired the harness and got it back running. Now when u give it throttle it either bogs down bad or starts to backfire. It never did that before the melt down. Trying to figure out what is going on and its driving me crazy. Any ideas?

Probably have to get a repair manual and start testing everything with a multimeter. Coil, stator, regulator, etc. I've never seen one fry a harness though without a direct short somewhere to ground and even then usually only fry the wire that's grounded. That's gonna be a fun one.

Yea i swapped coil with my other quad and same thing. It will idle fine for a few mins and then it will die out.if you slowly give it throttle it will rev up but struggles. Yea shorted the ground out and since they were all together took a feq wires with it.i was able to piece it all back together and she started right up almost like it is starving for fuel ot getting to much.just not sure which yet.
