Need help with fast idle cam not working
I have a Holley 4 bbl model #1850-3 with electronic choke on my '70 C-10 BB. The choke works perfect. However, the fast idle does not kick in when the engine is cold. I Have adjusted the fast idle adjustment screw in both directions (in and out) but it does not change the RPM. Should I be able to slightly rotate the cam by hand when I first cold start the engine and force an increase in RPM?
Any thoughts? Suggestions?
