Re: MG MIDGET 1500 1979 rough running

Hi Gary
It's a bit tricky to know where your problem lies without seeing the car! Have you checked the compression pressures? Does the Electronic Distributor you've fitted have an adjustable dwell angle and if so is this set correctly? The 1500 engine has a water heated inlet manifold and the steel pipe that runs through it, carrying the coolant, has been known to leak into the inlet ports-does it use coolant? Are the carburettor pistons free to move? Presumably you have the correct needles and jets fitted and plug leads in the right order.
Other than these things to check it may just want setting up properly.
Please let us know when you get to the bottom of it as we'd be interested to know what you find.
Good luck
