First of all I want to admit that I have very limited knowledge in regards to carbs...
My Mustang with a FRPP 347c.i./450hp crate engine,holley 750 dp mech secondaries and a single plane vic jr. has all of a sudden started idleing much faster. It use to idle around 750-800rpms's.
Now it wants to idle at around 1000-1200rpms.
I am unable to "blip" the throttle and get it to idle down.
It seems to also want to diesel or run on when I turn off the ignition. I imagine this should be expected when you shut the car off when it is idleing at a higher rpm.?
Do I just need to find the idle screw and back it down a 1/4 turn or so until I find the right setting?
Or could I have other issues?
Suggestions...
