I am restoring a 1955 Ford 850 and have completely rebuilt engine. The TSX593 carb was very rusty on the inside and I soaked it in rust remover and cleaned as best I could and installed a complete rebuild kit, but could not get the float seat and idle jet out. Cleaned the idle jet with a small wire and put a new float needle in. Reassembled the carb and checked to make sure the new needle/old float seat was shutting off fuel supply. Timed the engine at 5 BTDC statically and started the engine, ran fine but could not get to idle below 1100 rpm. Turning idle screw in/out had no effect. Replaced the carb with a new Zenith 13877. After starting, engine ran very rich (very black smoke out the exhaust) and runs roughly for about 10 sec, then quits. Check float level and OK. Idle adjust had no effect. This carb uses a fixed main jet so nothing to adjust there. So I put original TSX593 back now it runs rich, JUST LIKE THE Zenith!!!!! Now I cannot get it to run at 1100 rpm as before I removed it. Not flooding since no fuel puddles in bottom of carb.
I am completely baffled. Timing checks OK, good spark on all plugs, compression at 125psi on all cylinders. I am now grasping at straws. Can anyone offer a few more "straws" for me to grasp?
