My 1961 Ford 861 Powermaster began running very rough a while back, particularly when the engine was cold. I purchased a rebuild kit for the carburetor, a Marvel Schebler TSX 813. After everything was put back together, the best I could get it to do was fire up and run for 2 to 3 seconds with revving and some backfiring before shutting down, and this only after much cranking. Both the idle jet and main jet were one full turn from the bottom, plus some further adjustments to try to get it to run.
I disassembled the carburetor again and noted that the new float pin was longer than the original, resulting in the float resting at a slightly greater distance than the normal position of parallel to the carburetor body when held upside down. That would result in the bowl never quite filling, right?
I considered using the old float pin with the new float seat, but it didn?t fit as tightly into the seat, wallowing a slight bit side to side. Using the old float seat was not an option, it was all but destroyed during the rebuild.
I adjusted the float so that it rested parallel with the carburetor body, reassembled the carburetor, and remounted it. Now it does fire up smoother, but it takes a good bit of cranking. It doesn?t rev as much, now runs for around 3 to 7 seconds, but still won?t stay running. Any advice would be greatly appreciated.
