Hi my problem (among other things) was there was no metal weight filter attached to the of the end fuel line so the cheap rubber fuel line just floated to the top and was just sucking in air. You might try emptying the fuel tank and make sure there is a metal weight attached to the fuel line Other than that, if you're game, pull off the covers and check the other lines are not cracked or disconnected.

Hi Eric i can tell exactly what is wrong check your fly weel you will find the timing has sliped the wood ruff key way in the crank shaft moves which causes the machine to backfirs an will not start no matter what then you undo the bolt holding the flywheel on you will se on the washer it has been moving around you will need luck to repair i can tell you you more likely get the runaround buyer be aware
