Re: Vacuum Secondary Issues

Did you do a before and after test to check intake vac. signal?

The reason I ask this is because if you had, let's say 13" of vac. with the smaller carb., and now you have a lot lower vac. signal.....you may need to start at the beginning of the carb. tune and work your way up to the secondary circuit.
