You will have to determine if it is fuel related or electrical.......Try checking a spark plug wire with a spark plug grounded to the engine....spark should be present....If spark is present, try turning the ignition switch on an listen for momentary fuel pump run.....Turn off and on at least 3 times for start prime....Then try cranking......if no start, most likely a fuel pump problem...Depress fuel pressure port fitting for presence of fuel...be careful of the fuel pressure fitting a fire hazard exist....have a fire extinguisher handy when working with fuel components.......
Does it still have spark ?

Its just fouled some plugs again. Need an overhaul. If you just put a valve job on it it will just put more stress on the rings and will need it anyway. Not much you can do except change plugs all the time!

Try changing the fuel filter and checking the fuel pressure at the shredder valve. The readings should be 60 to 65psi with the fuel line pressurized with the engine not running, once the engine is running. It should drop by 5psi. Start with the simple things first. Keep me posted, be glad to help.

sticking valves. the short run of the engine free's them enough to enable runnig

Also check for tight fit of plug wires in distributor cap and coil .
Make sure oil level is correct...low oil sensor will disable ignition if more than a quart low..........
If it runs afta prime ull need a new checvalve tu hold fuel
