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.

what size carb. distributor? on points or magnetic pick up?

Posted by gypsy88 (Member # 13891) on :

I don't know how do I find out

Posted by gypsy88 (Member # 13891) on :

Would some pics help??

Posted by 4IDFOX (Member # 9921) on :

Could be timing as much as the carb.

Posted by Secnd2nun64 (Member # 1431) on :

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.

Posted by gypsy88 (Member # 13891) on :

It's a Holley 570cfm

Just got it back from being restored

Posted by acmikee (Member # 5568) on :

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

Posted by gypsy88 (Member # 13891) on :

Where do you put the vaccum gauge on.

Posted by kingdavid (Member # 11179) on :

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.

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

Posted by Tom Renzo (Member # 13165) on :

11 VOLTS!!

Posted by acmikee (Member # 5568) on :

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?

Posted by 4IDFOX (Member # 9921) on :

Does the distributor have points in it ?

Posted by gypsy88 (Member # 13891) on :

I think I have a timing light, where can I get a cheap vacuum gauge and tachometer?
