1966 rebuilt 289 bored to a 306, Holley 4 barrel carb. It is a fight to get it to start and stay running. Once it runs and i start driving it it hesitates when i hit the gas. Just wondering if the carburetor needs to be tuned and how to tune it.

Could be timing as much as the carb.

There should be a part number on the carb. Is this a new problem? What did you recently change to the engine? Post up some pics.

sounds like a timing issue. whats your timing set at put a vacuum gauge on it should read 18-19lbs.

I had an issue with my car years ago that was similar to the issue you are having and it turned out to be I was only getting 10 volts to the coil which made it run like crap and hesitate might want to check that also just a thought. [ 2014-12-29, 03:52 PM: Message edited by: kingdavid ]

Check the volt while it's running? What's it supposed to be?

put the vacuum gauge on any vacuum line or the base of the carb or tap into the pcv hose or brake booster.

Do you have a vacuum gauge, timing light and some sort of tachometer?
