Take off the float bowl and make sure the float valve is moving freely. if not, take the valve out, if it rusty, try cleaning it or replace it.

Have a Kohler Courage 18 hp in a Cub Cadet! SPEC PS-SV541-3212! Had bad gas! Dumped and put on a new fuel filter! gas! Did not run before without the choke pulled almost all the way! still same


Remove fuel line at carb. Remove filter, Drain out all old gas from tank. Let all of the fuel run into container if you see trash and water spray carb. Cleaner into tank until all trash and water are no longer seen. Blow out with compressed air if possible.Put all lines back. Remove bowl from carb. Check the bolt you removed from bowl should have a vertical and horizontal orifice through the bolt, make sure it is clean, remove all trash water etc. From bowl making sure the bowl gasket is in place and not pinched. Hopefully it will now start if not probably carb. Overhaul next.

It won't run and dumps fuel.I've dipped thecarburetor and cleaned it well.the fuel just runs out the lower spring covered house that dumps out onto the ground


The problem is a bit of trash is preventing the float needle from closing fully to stop the flow of gas. Try this; drain the float bowl then close the drain and turn on the gas. Tap the float bowl solidly with the end of a screwdriver handle. The object is to free up the float / shake loose the trash. If doing that a couple of times does not fix the problem, Remove the float bowl and spray the interior of the carb using spray carb cleaner. Pay special attention to the float pin area. With the float bowl off you should be able to gently lift and lower the float. Lifting should shut off the gas and lowering should let the gas flow again. If the float shuts off the gas when raised, put the float bowl back in place and see if the carb still over fills. If so, then the float is defective and you will need a new one.

My bike was running fine yesterday and i went to start it today and it will try and start but wont run. what could be wrong?


A likely problem is water in the carb float bowls. Water condensation in the gas tank can get to the carbs and will collect in the float bowls. Drain the bowls if a drain bolt/screw is present or remove the bowls and dump out the water. Also, is the kill switch on? Is there gas in the tank? Do you have spark? Did the battery go dead? Bad fuse?

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 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.
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.
