History: We bought this '73 2.0 last summer. It ran ok at the time, though on cold start-up it would choke if we gave it throttle before it had a chance to warm up for a few minutes. We dropped the drivetrain in the fall to do a bunch of general cleanup on the engine and trans, including:
Today: We finally got everything back together and started the car but it was running really rich, so much so that we could barely keep it running. After we shut it off it wouldn't start again. It would spin fine, but not even a hint of firing. Things we've done:
So first, I think it's so badly flooded that we need to wait a day and/or pull the plugs so that the cylinders dry out. Second, I'm guessing that replacing the hoses fixed a bunch of air leaks, which some PO had compensated for by richening the mixture. I could very well be wrong, just a guess. I've read a good amount and have a basic understanding of the D-jet system, but I'm looking for pointers about where I should start in fixing this. If I'm right about the flooding we should be able to get it started. Then what do we need to start checking to address the rich running? |

test the vacuum of the MPS
then the range of the CHT both of these can fail in a very rich condition also you may want to pull the injectors and test them... one could be leaking/open causing a very rich condition.... but usually that would only flood the offending cylinder.... where as the MPS or CHT would effect all cylinders |
