Question about ATVs
Having a hard time getting my quad to start. Replaced battery, just replaced the automatic choke. The carb has been profressionly cleaned twice. I have checked all 3 jets and cleaned them. Found them to be clear. Once it will start after trying for 15 to 20 minutes it will stay going most of the time. Once it's been running for awhile it runs fine and will start right up 90% of the time. I need help and am on a tight budget. Thank you. Ron

Hey Anon, It sounds like the "choke" system is not working properly,, hard to start until it warms up is "classic" choke system problem..

SOURCE: quad starts but won't stay on?
ALWAYS have a fire extinguisher at hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).
Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.
Please rate this solution. Thanks!

Sounds as if the gas tank is not breathing properly. The next time you run it, when it's about to die, loosen the gas cap. It should begin to run again. This is a sure sign that your gas cap is clogged. Clear gas cap of debris, or buy a new one.
