Autolite 1250 carb?

The United Kingdom Belfast Built Autolite 1250 is the OHV 1600cc/1.6 liter/97 cubic inch carb used on 75 hp net Kent engines. It was used from 1969 to 1974 in the bowl in piston OHV Kent, and on some Pinto OHC engines in England. It then got replaced with a Sonic Idle carb sometime in 1975. Its likely to be less than a 120 cfm at 3"Hg carb based on its venturi size, just like the early Autolite 1100 1-bbl 144/170 engines.
Autolite 1100/1101 Sizes and Applications
1.00 Venturi (120 CFM at 3" Hg): 144 Thrift Power Six
1.10 Venturi (150 CFM at 3" Hg): 170 Thrift Power Six
1.20 Venturi (185 CFM at 3" Hg): 200, 250 Six
1.29 Venturi (210 CFM at 3" Hg): 223,262,240,250, 1963-1969
When replaced by a 227 cfm at 1.5" Hg Holley Weber 2-bbl carb, the horsepower would go up 18% to 13 hp to 88 hp net on the OHC 1600.
Good thing is that they still use the US F stamp Autolite jet.
Its basically the same as the smallest American
