Hi y'all, new member here. I've got a 91 Big Bear that I bought knowing it needed carb work. The stock intake boot was trashed, bought a Chinese boot and carb too fit until I can track down stock parts. It runs, but anything past mid throttle,or in 3rd gear at speed, it just bogs heavily. If I get it spinning tire in the snow, eventually it just quits. Backfires and pops after running a long time. I've gone through the carb multiple times, going up sizes and down sizes in the carb. Even deleted the parking sensor, still no real improvement. Help a guy out! Thanks.

 

Hows the plug look? Sounds like a possible bad coil or stator.
