Which carb would you get?

The Street Avenger series of carbs are actually more easily adjusted than the sub ject carb of this thread.

Where the #3310 is a series 4160 which does not have a metering block on the secondaries and does not accept replaceable jets the Street Avenger Series is a 4150 series with a secondary metering block which allows for jet changes and it also comes with the quick change secondary cover to allow easy access to the springs.

FWIW, the Street Avenger carbs are rated by measuring the flow wet where as the older 3310 750 was rated with dry flow. These two carbs are very close in capabilities.
