I’m not sure what else to do or where to look, any help would be greatly appreciated. my 289 has had the following done: Rebuilt and cleaned the Carb, inside and out. Dropped the tank, acid bath cleaned and sealed Cleaned and restored the sending unit All new gas line filters (twice) for a tot…

When the throttle is opened does the accelerator pump squirt fuel down the carb throat?

I’d suspect a problem with the carb. Who rebuilt it? There are settings for float level, idling mixture, and perhaps running mixture. What the settings are and where the screws are differs depending on the make model and size of the carb you are running. If it idles smoothly but isn’t getting ga…

I rebuilt the carb and I believe it to be “balanced” in those respects. If I slowly depress it, I can get it racing pretty fast. No backfires though. I do hear a sucking/rushing air sound but no clue where from. Thanks for the response

I’d start with engine off, remove air cleaner, look down the throats and open the throttle. You should see a healthy squirt of gas in each throat. If not, you need a new accelerator pump. I cant remember if this one uses the plunger or the rubber diaphragm and lever. I think its the latter. Whe…

If it will rev, it is unlikely to be the distributor plate shorting out. Your subsequent posts lead me to also believe that the carburetor is the problem. The sucking sound when the throttle is slowly opened leads me to believe that the float is set too low. Remove the carburetor top and look at the…

Re that carburetor, I have assumed that it is the Ford 2100 2 bbl. Is that correct? And how was the float level measured and adjusted? And how was the float drop measured and adjusted?

Like Knox, I would focus on the carb…A can of carb cleaner and a gasket set does not result in a “rebuilt” carb… The carb should be completely disassembled, main jets removed, everything, and soaked in a can of “cold parts cleaner” for several hours. Then washed in hot water, then blown out with co…

“But the vacuum does advance the timing when the throttle is opened. Ported vacuum is 0” at idle and increases when the throttle is opened. It will drop to near zero at WOT.But low RPM response is great improved with vacuum advance on light duty engines." Not in 1967

You know that the exhaust manifolds are loose. Fix that before you try to tune the carb. As everyone else has suggested check that the accelerator pump is squirting gas.

“The exhaust manifolds pipes are falling off” No backpressure dude!
