engine dies when braking hard

My problem isn't completely cured but is 100% better now after adjusting the rod differently.

THAT WAS IT, but the flex wasn't closing the throttles, it was this:

I just have determined the problem lies in the accelerator pumps circuit. I had them adjusted per Holley's instructions, with a little pre-load, so the action is immediate. The problem was, when the brakes are on hard, the throttle linkage is tweaked enough to give a squirt of gas into the closed carb venturies. I tightened up on the acc. pump screw slightly, which gives a little clearance before the acc. pump is activated. This one about drove me off the deep end.

thanks for all the help,

Can you get someone to lend you a different carb.

You might want to consider the process of elimination. Swap out parts until the problem goes away.

Just the thought.

Good work! I must look at mine tomorrow. Please post on your "fix". Might be the same problem a lot of people have.
