Ok Well I have a 1992 Arctic Cat Jag 440 Special. I have a two carb set up. And the problem is... When im stopped, if i give it full throttle the engine bogs heavily and it stays below 4000rpm and kinda slowly begins to go. If I use 3/4 throttle it responds like it is supposed to at 3/4 throttle. When I am moving the same occurs. When I decelerate just by letting off the gas, the engine back fires a lot and does not idle, it just dies when the track stops moving. Once driving for a good 30mins it didnt do the quitting when it stopped but it still backfired and bogged. Now I just replaces the throttle needles and the "Jesus" clips as they were worn. It didnt fix anything. Any ideas?
