Take the gas line off from the carb. hold is down, gas should free flow out. If it don't you got fuel flow problem. IF the gas tank is above the engine and there is no fuel pump then it a gravity feed system. Start at the tank, remove it clean it, install new hoses, new fuel filter, and a gas shut off valve some where before the carb.. Prior to connecting it to the carb. stick a golf tee or pencil in the fuel hose that connects to the carb. put gas in it, turn the gas shut off valve on. Pull the plug and let fuel drain till all the air is out and connect it to the carb. Now you have free flowing fuel to the carb. If it don't start then go after the carb. again.

The main thing you need to know here is Kohler engines are extremely finicky about the kind of fuel filter they are fed with. If it is not a Genuine Kohler filter, you will have fuel starvation issues. Buy your filter only if it is a genuine Kohler brand filter. Cheap knock offs don't get the job done.

Thanks all, I'll be getting a new filter and fuel line tomorrow and see what happens. COOPER

Also, stick a pin into the little breather hole in the fuel tank cap, to open it. Leetle bugs like to lay their eggs in that hole, and it acts like a vacuum, and won't let the gas flow out of the tank. See if the machine will run with the cap off. With the cap in your hand, try to blow air thru the hole, or suck in thru it. If it seems blocked, probe it with a pin.
