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…

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…

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

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

If you have the original air cleaner assembly, put it back on and you will get warm air into the carburetor. Make sure the hot air tube is connected unless you have a steel pipe attached to the exhaust manifold choke stove. It may not help with your problem if the engine stalls in neutral. In that c…

You might check those distributors out Keith. Some early emission models had a retarding diaphram added to the normal advance diaphram but no distributor that I am aware of was designed to operate such that the timing was retarded when the engine was accelerated. And I am quite familiar with domesti…

“but no distributor that I am aware of was designed to operate such that the timing was retarded when the engine was accelerated.” MOST vacuum systems were designed this way as most use manifold vacuum…Some used “ported vacuum”, taken from a carburetor port that only delivered vacuum at part-thrott…

" but no distributor that I am aware of was designed to operate such that the timing was retarded when the engine was accelerated." There were a few systems that had dual diaphragms, but in most pre-emissions systems, vacuum was used to advance the timing. Under acceleration, there is less vacuum,…

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.
