Gents.
I just rebuilt and installed a holley 600cfm on my 350 chevy. Truck starts and runs well but I am experiencing a high idle issue that I need help with. During the warmup phase, the high idle is around 1500-1700 rpms. If you tap the throttle it will not drop down. After high idling for about 4 mins, you can tap the throttle and it will drop to a normal idle, around 750.
It has an electric choke.
Is there any way to reduce the time it is high idling? I feel like it is idling for a long time when it's not even that cold out.
