    Fuel, Air, Spark.
    Take the centre lead out of the distributer. If it fires then all good.
    Then take top of carby and pour a little bit of fuel in it. If it fires then check your fuel lines are not blocked and there is fuel through the in line filter.

    Thats all I got....

    Can you undo any of the fuel lines before it reaches the carby to see if there is fuel coming out?

    As Col said. Splash a bit of fuel in the carb throat and give it a spin. If it fires then its a fuel delivery issue.

    Have you used "Start ya Bastard"? Spray down the carb and you WILL get a spin. Essential to gat a tardy diesel into action.

    pull the wires from the solenoids and touch then back on the connectors while ign turned on. you will hear them click. this isg ood enough if they were working before.
    You should hear fuel pump prime as ign turned on IF you have electric pump. check by following fuel lines .

    Fuel will come out of disconnected line if electric and ign on.
    possibly weaker supply if engine mounted pump while only turning on starter.

    CAREFUL that you have a container to catch fuel and keep away from sparks


    check if engine will fire on a squirt of easy start

    Tried pulling the dizzy cap off & rotating the flywheel by hand to check that the dizzy IS actually spinning? May have sheared the drive gear at the base of the dizzy drive shaft....
    As Mike posted above....check the little carbon block at the centre of the dizzy cap - should be spring-loaded & protruding down so that it contacts the centre of the rotor button when the dizzy cap is installed.
    Also worth a check: the rubbing block on the points - the bit that contacts the lobes on the dizzy shaft - these have been known to fail/crack resulting in the points being closed no matter what.... Grab a torch , take the dizzy cap off & rotate the engine (make sure the ignition is OFF..) look carefully at the points - they should open & close as they pass the lobes -high points - on the dizzy shaft. If nothing is turning - drive gear is shot - if dizzy is turning but the points are not opening the rubbing block is shot ( or the base plate hasn't been tightened properly.......)
    Cheers, Mark
