Lately my engine when warmed up runs at a fast idle. I grind in all gears and I think it is because of the idle. I can return the idle to normal by pulling the accelerator with my foot or by pulling the throttle lever quickly. The accelerator return spring seems very strong and carpeting doesn't seem to interfere with accelerator movement. The accelerator pump is set on #2 winter position which may not be right because the weather is usually in the 70 degree range. Any ideas on what may cause this to happen?

look to see if your throttle rod is an aftermarket adjustable one-if so shorten the rod. also look to see if the carb linkages are free and operate smoothly with the linkages disconnected

The usual problem with a lazy throttle return is the spring on the throttle shaft at the firewall. The replacement, 48-9737, is $6 at C&G. This spring gets a lot of use, and may look good, but eventually loses its tension. I've seen more than one old Ford with a piece of screen door spring attached to the throttle linkage to fix the problem. Also, be sure the two eye bolts that hold the shaft to the firewall are in position and not binding the shaft..

I took the throttle rod off and it wasn't adjustable. The return spring did seem weak. I resorted to Super's comment on the screen door spring but used a bungee cord and it returned the idle to normal all the time on a short ride. I'll replace the return spring. I'm still getting some grinding when shifting so I'll adjust the clutch too.
