My '73 has a Holley 650 double pumper with electric choke.
When cold starting, I turn the key to on, pump the accelerator once, then crank the engine which fires up immediately. The engine rpms begin climbing fairly quickly and will continue to climb until I blip the throttle at which point the engines settles in around 1500 rpm (if I did not blip the throttle the engine rpms would climb well past 3000). After sufficient warm up time, I blip the throttle again and the engine settles in at normal rpm.
Question: What is causing the engine to run past 1500 rpms on cold start which requires a throttle blip to settle in at 1500 rpms until warm? Is this a choke adjustment issue?
The engine runs fine otherwise and I have no other issues.
Thanks,
DC
