If you're going to try and tune the carb, don't forget the step-up springs. They can make a big difference in how lean/rich it runs.



This is probably the biggest oversight by many. It's the equivalent of the Holley powervalve.

I ran a 750 Comp. Series Carter for 14 years on two different cars. A great street/strip carb that is fuel efficient too.

The metering rod plungers would occasionally seize in their bores and it would idle rich but other than that never had to do anything after tuning other than change a needle/seat one time. Jets are easy to change, no fuel spill, metering rods change in seconds. Pump squirt selection and adjustment is limited though.

Good for mild-to-warm street driver, street/strip cars.

My 69 RR got 14 mpg and ran 13.70's at 103 mph on street tires with a 383, single-plane, 284/484 MP cam, headers, 4 speed, 3.91, 28" tire.
