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?

Yep, I cleaned the carbs. Im thinking that I should drop the pin down a notch in each carb. Maybe the sled is getting to much gas and drowning...

If the plugs are nasty oily black, it's over fueling somehow. THe needles control fuel on acceleration, main jets control fuel at full throttle.

same problem

I was having the same problem with my 98 jag. I just changed the spark plugs and it is running perfect. They were oily black but now it is running like a top. Change em for sure.
