Secondaries - Carb problem?
Sup,
Is there a way of knowing if your secondaries are opening?
Both of the T/As have 350s in them, but with rebuilt stock qjets. The vacuum system is all a mess on both cars (shop did it, wasn't my choice). They both run, but I'm not sure I'm getting the proper performance out of them. (tied a stock Subaru Forester H4 with 5spd manual with the 700r4 83' from 0-60, yeah thats pretty bad)
Any ideas?

Re: Secondaries - Carb problem?
im in the same boat with you man 0-60 in like 9 sec. on a 350 thats terrible. I would also love to know the answer.

Re: Secondaries - Carb problem?
you can adjust the secondaries to open up sooner. i just did it the other day, and it's really easy. it's the first section in the link called setting air valve (AV) tension. i actually noticed a difference afterwards.
