Loosing RPMs when i press the brake **Update**

[fordconvert]

1400 must be your 'normal' idle with that cam and stuff?

Thinking out loud here just in case it will inspire someone in the right direction:

Could there be end play in the dizzy shaft that is changing the air gap between the magnet ring and the pick up thing in the petronix? Still wouldnt explain why the brake would change it...

How did you do your throttle linkage/cable? Is it possible that there is some flex in the firewall or your cable mounting brackets when you push the brake pedal? But if you are already at 'base idle' on the carb slack in the linkage should not bother the speed...

Im out of ideas, Cant wait to see how this comes out.

yea we have the idle set at 1400 and i modified the stock linkage to work with the 2brl along with adding a few things to it its kinda hard to describe

well i got really busy yesterday and didnt have time to test anything but this morning on the way to school my car didnt idle at all and the same thing this afternoon on the way home and that made it a pain in the arse to drive and keep it running but i have learned pretty well how to use my left foot to brake around the clutch
