Greetings, Thank you for reviewing my first post...
I just purchased a 65 FB with 200ci engine with holley 1940. The short story is the car hasn't been worked on in years. It ran when I got it last week but not well. It was tough to start and stalled sometimes in the neighborhood. I took some time this past weekend to improve it but have run into an issue and hope somebody can confirm my suspicions. It ran in the driveway after the tuneup and warm engine but now when I just touch the accelerator after a cold start, the engine dies. My guess is the carb needs to be rebuilt - bad/dryrotted accelerator pump and now I learned it may also be a load-o-matic mismatch.
Status:
Compression 150ish on all cylinders
New spark plugs
Vacuum advance doesn't appear to be working on the distributor - when I disconnect the line to the carb there's no noticeable difference - considering petronix - should I still fix the advance?
Adjusted the max vacuum via the carb to get 21hg
Fuel filter and air filter haven't been changed in years (replacements ordered)
I haven't adjusted the timing on the distributor
Discovered this morning it's a load-o-matic C5DF-12127-E
To start the car I pump the accelerator 4-6 times and with the accelerator released I turn the key and it starts up right away - no issues. As soon as I touch the accelerator it dies. I'm used to seeing a spray of fuel in the carb when you hit the accelerator but there's more of a slight dribble in this car. Car won't start with the accelerator pressed.
Does this sound like a carb rebuild to you? That's my guess. What are my options on the 1940/load-o-matic. Can i buy/install a spark control valve?
