On the 1 bbl (Rochester BV I assume?)
Before you give up:
1. They MUST have a good pump shot. If you floor the carb in your hand, the squirter should still be putting fuel in nearly all the way to the floor.
2. They like a high float setting. I think it says 9/32", you can go as high as 5/16" but no higher or they will hesitate.
3. They like rich jetting, 59 or 60 jet at least - especially with today's "blended" gas which has to be jetted richer anyway.

On the 2bbl
x2 on that little progressive Holley/Weber/Pinto progressive 2bbl carb. It is a great little carb and excellent on gas too.
On a stock 230 that is exactly the one to run.
