I have the same problem, no fuel being sent to the carburetor. With starter fluid sprayed into the carburetor the engine runs for about 5 seconds... so not electrical. I disassembled the fuel lines and all were clear, there is fuel visible in the fuel filter. I finally replaced the mechanical fuel pump. Engine still will not start. I removed the fuel pump outlet hose and cranked the engine, no fuel is being pumped out of the pump. I poured a little gas down into the outlet; cranked the engine and no fuel spit out. Any suggestions? Engine is Kholer 17.5 HP OHV for John Deere L110 (purchase approx. 2004).
