I just picked up a 1940 Ford that is a older restoration. the car idles fine but will barely rev (can hold it wide open in neutral and I don't think it will go high enough to hurt it) . No black smoke or any kind of smoke. So far I have blown out the fuel line to tank (new tank) Dissembled and cleaned the entire carb. Checked that the fuel pump was supplying fuel. Filled with fresh fuel.
What carb is on it? Is the timing set right? What distributor is in it? Cam/compression? Valve adjustment? Timing chain/ base timing ok? Have you hooked up a tach or timing/dwell meter to confirm rpm ?
I have had it for about 2 hrs. it is all stock except the coil that is a modern 6v coil. i will say the valves are quite. As for checking the rpm you can hardly drive it so it isn't much. sorry I don't have more answers yet.
Check the dizzy make sure it is getting vacuum from the carb also look inside make sure everything is tight and working properly the dizzy will give you fits
Condenser will do that. Cheap part to throw at it. Sent from my SM-G955U using The H.A.M.B. mobile app
If it's not misfiring it could have a restriction in the exhaust. Seen late model vehicles with plugged cats that ran fine but wouldn't rev.
Is the linkage bent? Have someone hold down the gas pedal which you check to see if the butterfly on the carb are all the way open Charlie Stephens
Bingo, go to napa and buy a rr175 and replace the condensor on the coil adapter. should do it???? Let us know......
Ok Bubba I finally got around to trying this and no change. also bypassed the fuel pump with a 6v electric. Still nothing
Let’s totally eliminate the fuel system. Place a fuel can above the carburetor. Hook up a line directly to your carburetor or attach a hose to a hard line at your inlet. I’m thinking carb issues but this will eliminate a blockage that comes and goes or maybe not enough fuel volume.
