MYBLUEHEAVEN

I know this question may have dozens of possible answers, but hoping I can use some of the simper ones. My recently acquired 1965 327/300 appears to have the stock Carter carb. Can't seem to find a model number or I would include that. Overall, car runs great except if I'm too aggressive going to full throttle, the acceleration bogs down (sometimes a little engine cough or"chuff') then it seems to gather itself and accelerates. The accelerator pump gives a full stream throughout the throttle range. Could the secondaries either open too early or too late and are they adjustable?

Also the speedo cable jump slightly at lower speeds. To lube the cable does it have to be completely removed at both ends? Please advise on the proper steps to lube the speedo cable. Thanks again.

Speedo cable core lube: Pour about 1/4" of engine oil in bottom of 3# coffee can. Disconnect cable in back of speedometer and feed core into can. Feed core back into casing and reconnect to speedo. Your're all done.

Carb trouble: Heatriser passage blocked open? Heatriser been removed? (Location: Lakewood CO, maybe cold there yet?)

When do you think the carb was rebuilt last? Send it off to get redone or put another carb on.. Dave

It turned out to be just the mass airflow sensor. Changed the plugs and wires first (it needed new ones).
