I have a 1965 Mustang with a stock 289. I just installed a new Holley 2 barrel model 350. I went with a manual choke. My problem is that the idle is running at 1200-1500 rmp. I turned the curb idle screw completely out and it makes no difference still 1200-1500 rpm. I have tried different scenarios, warm motor, cold motor, and with the throttle plate in various and in its appropriate position. So my question is what would cause the idle to rev so high with the adjusting screw turned completely out.
I appreciate any input anyone can give, I am at a standstill....
Thanks
