Carbking, You know, as I was tossing and turning in bed last night about this headache, I was giving some thought to your post above. As a novice, I have given little thought to the interplay of the tranny with the carb. I was reviewing in my mind everything that I did to my truck between the time it ran well and the time it stalls at braking. And with your post in mind, I wonder about the following:
When I acquired this truck it ran perfect. I mean puuurfect. Recently, on another forum, when I happen to post photos of my engine bay, a member with seemingly impressive knowledge noticed that my vacuum configuration was not correct. That is, I had the pcv sharing vacuum with the brake booster, and I had the tranny on a private vacuum line, and I had the dizzy on a private vacuum line. He said I must change that. That the pcv should have a private vacuum line; the brake booster should have a private vacuum line, and the dizzy can share vacuum with the tranny. So I rearranged it all to conform with his advice. Carbking, do you agree with the foregoing, or do you have a different opinion? I have not yet gone back to the initial configuration because it is rather tedious, but it is a fact that, since rearranging the vacuums (and swapping out a bad balancer on the timing gears), I have this problem.
