Engine Stalls...
 

Experiencing a stalling problem with one of the L78 4spd cars. Seems to be fuel related from where I sit. Car stalls when you brake for a stop, but starts right again up when you hit the key. Runs fine down the road but feels a little funy when you hit the brakes. I checked the front bowl float level and appeared to be ok. Didn't check rear yet. Any comments...

Power brakes? Leaning out fuel when brakes applied? Richer fuel mix or higher idle speed?

Don't overlook a loose wire or ground shorting out when you apply the brakes.

Maybe a internal vacumn leak in the power brake booster that only shows up when you apply the brakes. I would try taking off the vacumn hose to the booster and capping it. Then drive the car and see if it still does it when you apply the brakes. Just remember that your brakes aren't going to work very good.

Maybe float level....

Sounds like a float. Sometimes the brass floats will give it up.

Check for pin holes in the float.

We had a similar issue in the '70 after we changed the carb. The float would fill up with gas and sink. There was no gas coming into the bowls. It could be a similar issue. Every time we would move the car or come to an abrupt stop the car would stall.

Dan you got me scratchin my head...A float that don't float floods the carb...if its set too low it will uncover the primary jets on a hard stop... https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Charleys vacumm advice is a good one...we just had the booster crack in my bro's truck..it was erractic when it first failed.

Thanks for all the input boys. I will try the vacuum hose test first and report my findings.
