Hey all, I'm trying to get my 12a to idle at 750.. I finally found the idle speed screw hidden under everything.. its hard to get mine low without stalling.. I got it to idle about 900, but it keeps speeding itself up to 1000 every couple seconds....

Vacuum leak.. ??

 

Most likely. There is a link in the archives to the FSMs, in there is a seperate carb manual that covers the entire run of 1st gen carbs.

 

i can get mine to 700 before it gives me trouble...... makes my car sound like it isnt even running... i love it

 

very nice! I want mine like that

 

if u had an 80, maybe it would be! hahaha. i cant wait till i rebuild it..
