Trying to figure out why I have such a low vacuum from my front HS6 as I do from my rear. My synchrometer registered an 8 on the rear and a 2 on the front. I know that it's all relative to the tool but that's a lot. I've been able to even it out by increasing the idle and increasing the enrichment but that's not a long term solution.

The linkages were all detached including the carbs and the accelerator. Jet flats all at the same number of turns. Did a dry compression and all my cylinders were around 155psi from my B20B low compression head/B20 block. Couldn't see any vacuum leaks but I couldn't get under the car.

Any thoughts?
