Today I am going to adjust the timing of my engine
but before I do I want to know how I adjust the idle speed
Where do I turn the screw clockwise or counter clockwise?
Oh and what's the idle recommendations? Right now its at about 800 rpm
My 77 Ford F150 4x4 has a 400 with 2 barrel 2150 carb and C6 Auto the Ford valve sticker is still on it. It specifies 650 RPM curb idle with the truck in neutral with the idle solenoid wire disconected. I used the screw on the drivers side to adjust idle with a tach hooked up at the coil after the engine was warmed up and the temp guage up at the middle
