A 632 BBC, with 10/71 Littlefield blower and Enderle alcohol injection. Starts and runs awesome, sounds like angels singing. But it doesn't want to settle down and idle. RPMs keep creeping up, idle speed adjuster doesn't help. Trying to help someone who inherited it, neither of us know much about it. Just want to be able to run it to show potential buyers. I have found papers saying it was set to 68% @ 100 psi, Idk what that means but I take it for idle mixture adjustment maybe? Any help is greatly appreciated.
