My atv will not crank over. Ran well days ago no can't get it started. Changed plug and still not turning over. Back fires once in a while. Open to advice. 2002 sportsman.

Won't start

Pulled plug and got good spark. Seems like it is not getting any gas. What would be my next thing to do?

Seen many times carb popped out of boot at the cylinder. Check there and If still no go pull the bowl off the carb and see if any crud made it in there

New to world of atv. Is the carb behind the plug? Just checking to be sure. I believe I found it but nt to be sure.

If it's back-firing it's turning over

Carb should be under the seat between the air box and the engine. It will have a black fuel line running to it from the fuel pump. If you pull that line off the carb and turn the key, gas should squirt out of it (not just slow drip).

How is the gas flow to the carb? Does it spray out or barely trickle?

Back to the basics. If you hold the coil wire close to ground do you get a spark when you crank? Pull the plug and put it in the coil wire and crank it. you should get a strong yellow/blue spark across the electrode. Is the plug wet with fuel or dry? If you're getting a strong spark, put it back in the engine and spray some carburetor cleaner down the throat of the carb and crank it. If it fires for a second or two then you know the problem is fuel.

If it idles for a second or two on the carb cleaner then you're not getting fuel. Float valve could be stuck closed, or the idle jet could be clogged.
