Does it turn over???
Yes.... Check for spark
No... Disconnect the battery trying turning it over by using a socket on the harmonic balancer bolt
If it does not turn after trying to turn the engine over disconnect the pump from the engine and try again one of the 2 may be seized
did you do anything to the engine after you shut it down off after running?
?
Check to see if you have spark first.
Yes..... Check carb to make sure it pumping gas
No.... Recheck all your wiring for your distributor and coil....and if you have a ballast resistor is it good... check your points also make sure you're coil is good if running electronic ignition are you using correct ohm coil
Engine gots spark move on recheck your firing order make sure all the wires are where they are supposed to be set it at Tdc to number 1
Got gas... Make sure you dont have fuel pouring out to much coming out will flood you out and the engine will not start ... Take off the air cleaner or scoop do not start your engine yet look down the carb while some one presses the gas peddle you should see fuel spraying out if
not there's a carb problem or obstruction in your fuel supply check fuel water separator and fuel filter
If you have spark, gas and timing is correct check your valves make sure if you set them correctly if you're running a hydraulic flat tappet cam be careful of how much lift you're running and you're spring pressure the cam will go flat quick but good luck
