with the rocker cover off turn the motor to top dead centre
check to see if the cam lobes on number 4 are actuating both the intake and exhaust valves(rocking between the 2)
now turn the motor back slightly so it is on 6 degrees before tdc .make sure that the rotor button is pointing to number 1 spark plug lead on the dizzy cap.if not then turn dizzy till it is, or put leads onto cap remembering that timing is 1-3-4-2, and it turns in an anticlockwise direction. if this doesnt work.. goto a mechanic.. do not pass go and do not collect $200
