Engine stalls out.
Have 1966 F-100 300CI 6
Just rebuilt Ford carb,single barrel but runs same as the old Holley carb only worse
Starts fine and responds to the manual choke but as I increase the RPM it seems to miss and bog down. Checked timing, vacumn advance, fuel supply, all OK. If I did not know better I would say there is an ail leak in intake.
Any ideas anyone? Slowly getting every things fixed.

Jet #69F / 0 to 5,000 ft altitude = C3TZ-9533-B (Motorcraft CJ-132)
Or (depending on the carb ID tag) >
Jet #68F / 0 to 5,000 ft. altitude = C3TZ-9533-F (Motorcraft CJ-149)
Jet #67F / 5,000 to 10,000 ft. altitude = C3TZ-9533-C (Motorcraft CJ-139)
Jet #65F / 10,000 to 15,000 ft. altitude = C3TZ-9533-A (Motorcraft CJ-131)
Carb Kit: C8OZ-9A586-D (Motorcraft CT-207-A)
Float: C3AZ-9550-A (Motorcraft CM-430)
Acc. Pump (also comes with kit): C3AZ-9B559-A (Motorcraft CM-432)
