I'm new here so forgive me if I have posted this in the wrong forum. If possible, please help:
My 1974 Merc 280 had a problem starting the other day following lots of rain. The next day it started right up and then stalled after a minute. I thought it was an electrical issue so I gave it a new distributor cap, rotor, plugs and wires as well as a new air filter as the old one seemed to have melted a bit. After changing all that it started and ran like a champ until I tried to drive away. It backfired through the carb and stalled. Since then I have gotten it to start again and run for about a minute then it suddenly cuts out as if I turned the key off. Occasionally it will bog down and I can keep it running for a bit by giving it gas but it still stalls in the end. After stalling it needs to rest for a few minutes before it will start again. The choke and carb intake were sticky so I sprayed them with carb cleaner and they seem to be moving fine now. I'm at a loss for what to try next; thinking fuel filter, fuel pump relay, points, coil, carberateur???? Any suggestions would be greatly appreciated, I don't want to have to put it in the graveyard. Thanks in advance.
PS. I have the same shifting problem mentioned by ward in the beginning of this thread... what was the fix?
