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.

Sounds like a vacuum leak.

Going to try spraying something around carb and intake to see if it changes rpm.
Another thought is the size of the jet in carb. manual says 69. The one in the first holley was 62.

Does it do it once the ewngine is warm. If not just warm the engine. or rich the choke slightly.
