UPdate:
Someone a while ago told me to plug two of the three idel circuits as only one will be needed. That was false. The truck could not run on just one idel circuit, and backfired to beat the band. I unplugged them both, and wal-la, it's running much better, good idel, and no backfiring. I took Carbkings advice and removed the linkage, balanced out the airflow, and got the carbs working together nicely. Now that my linkage, idel circuit are working properly, I have another problem. The truck has a hesitation particularly on hills, or lower in the RPM's. A friend mentioned that it sounded like it was running lean. Can anyone provide guidance on how to determine this, and what steps to correct? FYI, my setup is a GMC 302 straight 6, with three stromberg 97's on a McGurk Log manifold. If anyone is interested in my project, check out my webshots at
