Edelbrock Carburetors?
I put a vacuum gauge on mine a few minutes ago and before I cranked it, I swtched the step-up springs to the strongest springs (8 in w.c.) available in the calibration kit. In the Edelbrock manual it says to use a spring that is ~ half the manifold vacuum.
Cranked it up and not warmed up it idles about 16 inches. Once mostly warmed it increases to 17 inches. So, based on the Edelbrock carb manual, I made a good move on those springs. I didn't get to drive it as it is raining and I just cleaned the Scamp on Sunday! I doubt it's going to get me as rich as I would like, but maybe it will help the 1.5 second lean spike.
Idle AFR's 13.0 ~ 13.7.
Idle Vacuum 16" ~ 18" but spends the majority of the time on 17".
Idle Speed ~825 rpm.
Comes right off idle great. At that level of vacuum (correct me if I'm wrong) I think it indicates that my cam is not so aggressive. I'm starting to get addicted to this stuff. Am I being seduced by the dark side?
