okay last nyt managed to get it going after jump starting it down a hill, although a little underpowered still runs (im guessin just needs a good run, clear it out)...today same problem, wouldnt start again but would jump so im going to change the dizzy cap, rotor arm, ht leads, spark plugs tomorrow. if that fails, based on elimination that should just leave the ignition coil?

if that doesnt work then i dont know what else could be causing it!
many thanks
