Carb is running too rich!

[OLDFLM]

Start with all four idle/air screws 1 turn out... set your idle to 1000rpms. Verify TDC... did I mention "verify TDC"? I know you put the timing tap on their but it doesn't take long to verify TDC.

How much mechanical/vacuum advance do you have in the distributor? If's it's 12-14* set your initial timing to 18* for 30-32* total... you can verify total by holding the rpms at 3000rpm and checking your timing. It should be "all in" by then.



You'll need to know how much advance you have it you want it to run well down the road... you may have to start by verifying total timing... then check your initial so you know what your mechanical/vacuum advance is.

What type of distributor do you have btw?

Back to the carb:

Adjust your idle screws... check the vacuum gauge... adjust the idle back to 1000rpms... adjust idle screws... check the vacuum gauge... adjust the idle back to 1000rpms... repeat as necessary.

Shoot for an AFR of 13.2 in park should get you to 14.0 when driving.
