Good afternoon. I’ve been working on a MEP-003a for months now and can’t seem to figure out the problem. The engine starts and runs fine but after a few minutes it develops a miss. I have replaced the injectors, injection pump, fuel lines, fuel line check valve, fuel pumps. I have done numerous valve adjustments and timed the injection pump multiple times. Fuel pressure to the injection pump is good. All the filters are new. I have also done a compression test on the engine and the numbers are great. Any direction to look into would be greatly appreciated.
