I am new to this forum. I have been having some issues with a 1984 200es I bought. It started and ran good when I first picked it up. Ever since I have been having intermittent problems with it. It will start and run for 5-10 seconds and die. It doesn't do it all the time and once it runs it will run and drive great. It did die randomly on me once when driving. I have tried a few things I bought a new mukunni carb, new battery, new plug. I also adjusted the valves and the timing advance. The compression is good. It sure seems like a electrical issue. It will just die and not sputter or bog first. I'm not really sure where I should go with it from here. Any advice would be greatly appreciated
