Small Engine Troubleshooting Problems? Ask a Mechanic Now.
The older two cycle, single cylinder ,or the later twin 4 cycle engine? Are you getting fuel to the carb from the fuel pump when cranking?
Here is link for the carburetor. Just so you know, what you can buy one for! But check the fule flow, it does not need much, 1/4 cup in 30 seconds would be plenty. Check the fuel supply from tank to the fuel pump. You may have a blockage before the fule pump.
Four cycle, no oil in gas or oil injected?
Can you find engine model number? This late model usually has the 295 cc 2 cylinder engine.
If it is the standard engine, it is a timing belt engine, and you could have a timing belt that has slipped. Like link below!
Single cylinder, gear timed engine, no timing belt. Valves set at .004 to .006 inch. Coil and flywheel magnet is all that makes the spark. Manual on the engine does not show fuel pump. Is this a pulse pump. or electric fuel pump? Does engine die? How long before it will restart? Does it have spark when it quits?
See the PDF , second one listed? That is service and parts manual, you will have to download it. above link.
Pulse pump. Ok, so you are going to replace the fuel filter.
