@t663s33, Fred Clevenger, You did not state your year/make/model/engine so I will post some what generic answer on fuel issue. Ensure you have good fresh gas and that there is fuel flow from the tank, as there may be an internal screen in the tank plugged. If the engine has a fuel pump, you should not have to prefill lines/filters. Now assuming the engine was running good right up to the end of last season, I would think the engine to be OK. There is a possibility that the carburetor could be dirty or the float stuck not allowing gas to engine. If you can remove the air filter from the engine and squirt about 1/2-1 ounce of fresh gas right into carb.. If engine starts/runs then quits when the added gas burns off, the problem will probably be dirty carb. since you have already addressed filter, fuel lines, pump. If problem persist after carburetor cleaned/rebuilt the new pump may be faulty, vacuum line to pump pinched or plugged. If all looks good and still no go, have the compression checked on the engine to see if rings/pistons worn or possibly valve sticking. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
