The Stovebolt Site Forums The Shop Area Engine Shop Engine bogs/stalls when braking.

Use a wire to by pass the ignition switch and go straight from the + side of the battery to the + side of the coil and see if you still have the stall. This will by pass the electrical circuit under the dash. You can run it for a few minutes this way to see if the stall continues. If the stall continues then go back to your regular wiring.

If there is a wire bad under the dash, it may be losing contact under hard braking conditions. Might be rare, and may not be that at all.


Make sure distributor advance vacuum source is ported vacuum. You may have to adjust the timing to compensate if you have the advance hooked up to full time vacuum source. This will tend to advance the timing at idle, yet when vacuum drops will retard the timing until the mechanical advance can do its job.
