HELP please, Gotta go to car show this weekend but all of a sudden she won't idle, mid/hi speed ok, took top off, all ok, blocked off all vacuum ports, fresh gas??? Thanks.

 

Did you try adjusting the idle screws? I'm guessing you did, as well as the fuel filter. Do you have a vacuum gauge? Make sure your distributor vacuum timing cannister doesn't have a blown diaphragm, leaking vacuum. Commonplace on old cars, simple and cheap to replace too.

 

Thanks, chkd all but Disto Vacum adv, good call!

 

Thanks, macbubba. I am not a young man anymore, so searching for vacuum leaks is par for the course
for an Old Guy like myself!
