Re: When I apply the brakes my idle drops too much

Set your idle when hot at 750 rpm.
Then check your initial timing.
If it’s below 10 degrees bump it up to 14 degrees. Plug off vac advance line doing that.
Check your idle is at 750 again.
Adjust your mix screws.
See how that works.

Is your vac advance hooked to ported or manifold vacuum port?
