My car is demonstrating a tendency to die on hard braking. My understanding is that causes typically fall into one of two categories:
1. fuel sloshing over from rear float
2. vacuum steal from power brake booster
My cam is a fairly aggressive Comp Cam 292H. I'm generating 7 inches of vacuum at idle and at least by my gauge there doesn't appear to be any vacuum leak. Idle speed is about 800 rpm. With that low vacuum I would think I would be at risk. I haven't noticed anything abnormal about the feel or performance of my power brakes.
The rear float is set at a level just a hair below the site window. I know I've got some heat soak and percolation issues going on at the carb. The stalling seems to have gotten worse as the weather has gotten warmer. Could heat, evaporation and condensation of vaporized fuel be contributing to the problem?
First, I'm going to try dropping the float just a bit. I've also got plans to add a carb spacer but that plan is on hold while I decide what to do with my intake and air cleaner.
Any other thoughts or recommendations?
