2005 Yamaha Bruin 350 ATV. What will cause my ATV not to run? Gas is coming from drain tube?
Question edited for clarity.
Question moved from motorcycles to ATV model category.
Turning over has nothing to do with the carburetor! Your battery is flat. It will need charging.
If the carb is leaking, it is because the float is set wrong or the float valve needle isn't seating properly.
Engines only need three things to run.
A supply of clean fresh fuel (not sitting a year)
A Spark at the right time.
Compression.
You say you cleaned the carb **in** carb cleaner, as opposed to *with* carb cleaner. Did you strip it down, check the float for holes, clean the jets and needles?
AMT 622 motor doesn't run smooth.
1992 last one made, ever see it run good? if yes how long ago?
A MISFIRING ENGINE IS EASY TO HEAR, FOR SURE 10HP KAWA
kawasaki FE290D, gas engine not diesel.
bad spark plug
or bad gas.
or carb failing.(way too rich)
if engine runs smooth heard to, then CVT fails, bad belt?
or the CVT controls are failing. overloading engine with wrong RATIO
up hill.s.

I have a 2005 Polaris 700 EFI. Recently it has
mine did the same thing & then it finaly quit running altogether...the gas gauge stoped showing in the display also. I pulled the old fuel pump out & replaced it with one out of a 97 ford areostar witch has an almost indentical pump & now the machine runs like new...and my gas gauge started showing again & I saved myself 500 bucks because the pump i used was gave to me...lol

2005 Polaris Sportsman 700 won't start.
Go back to basics. What EXACTLY does it do when you try to start it? Just spins it is often No spark. 'Coughs' and tries to start is possibly a fuel supply issue.
An engine needs 3 things to run. Air, Fuel, Spark. Did you check for spark on both cylinders?
Have you checked the air filter is clean. You will be surprised at how much a dirty one can affect an engine.
Have you checked for fuel supply at the cylinders. If you can get your head near the plug holes try this. Remove both spark plugs. Crank the engine for 2 seconds then remove the ignition key. Sniff the spark plug hole. Does it smell of fuel? Do the same for the other cylinder. Use the comment button below and I'll see if I can help you more.
