just rebuilt.. street ported.. the works.. when warming up its fine nothing wrond but when its opperating temp and its kicks down the idel it trys to stall for a few secs and then it does... any ideas what this could be.. fixed a few jetting issues, was runnign to rich but now its good.. i just need to figure out why it dies.. any ideas.. almost everything on the engine is new.. thanks in advance!

 

How fresh is the engine? If it's still in the running-in stage it might just need to wear in a bit, especially if you have new seals on old rotor housings.

Mine was like that at the start as well so I had to keep the idle speed bumped up for a while to keep it from stalling.

The only other thing the comes to mind is the carb. What are you running BTW?

 

Check for vacuum leaks too.

 

RB Holley 650 I beleive
