1974 MG Midget failure to re-start

Hi there,

Thank you for the donation.

Check spark when it won't run by first checking for voltage at the Pos side of the coil, if this is ok, remove the distributor cap and turn the engine by hand ignition off till the points open, check the gap about.012" should be ok, I will need to find the exact specs if you need them. Place the test light on the neg side of the coil and turn the engine by hand, check that the light goes on and off as the points open & close, on No 1 check that the timing is around 5 Deg BTDC when the light goes on this is static timing, if the coil is very old replace it as it may be breaking down when hot, this can be tested on an oscilloscope, as for the fuel system, make sure that the carby has adequate fuel supply, check these basics first.
