Carberator gas bowl drain tube leaks gas. Screw is tight. Sorry I couldn't find an atv category.

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?

Vehicle information needed

you adjust it by bendng the small tab on the float that presses on the end of the float needle,to check it is right find a length of clear tubing and put it on the small pipe bit that is on the bottom of the float bowl ,then bend it around the carb and point it upward s,then undo the drain screw on the float bowl and the fuel will come up the pipe and when it stops that is the same level as the fuel in the float bowl.its usually about 2/3 of the way up the float bowl.to low and it can starve it of fuel and too high it will flood and leak out.

On the bottom of your carbeurator (very bottom of the bowl) there should be a drain screw/plug. Turn the fuel petcock off, then loosen the screw to drain the sediment bowl. When it is done draining, turn the fuel back on and let it drain through for a second, before tightening the drain screw. The bike might take an extra few seconds to start, just needs to refill itself with fuel. This usually resolves that problem, i've had it happen on many ATVs/Motorcycles in the past. Could be water or sediment in the bowl, or a sticky needle valve. Good luck.
NOTE: use care when draining, about a cup of gasoline will be lost; use a container to catch fuel.

If it's leaking from the bowl drain, the drain screw isn't seating in the drain hole. Shut the gas off, pull it out and clean the tapered seat it seals in. I know you said you cleaned the carb, but if the float needle isn't seating, it would leak out the overflow and flood out the carb as well. Check out the float-if it's brass, shake it and listen for gas inside. If it's plastic, put it in a cup of gas and see if it floats. They do get saturated over time and need to be replaced. Good luck!

Tap the bowls with a screw driver handle while the gas is turned on. Your floats are sticking. If that doesnt work then you have to take the bowl off and make sure your floats are not bent.

You have a leaking fuel valve in the carburetor bowl.

ALWAYS have a fire extinguisher on 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 may 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. 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.

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. Before putting the slide back in the throat of the carb, move the clip on the jet needle one notch lower. 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.

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.

Set the idle speed with the idle screw. This process should get you back on the road.

Since you mentioned uneven idle revs, be sure the carb and manifold are on tight and also tighten the cylinder and head. Air leaks can screw up the idle.
