Default Throttle lever problem

My throttle lever won't overcome the pressure of the main gas pedal linkage spring with the result the lever just slips back to the idle position when I let go of it. Yes, the detents on the throttle quadrant are worn but not so badly that the lever shouldn't at least try to stay put where I position it. The throttle lever linkage pulls on the main foot pedal linkage to set the engine speed and this seems to be the way it is supposed to be. However, the main linkage spring seems to be too strong and forces the throttle lever back to the idle position. On the other hand, there does not seem to be any abnormal effort to push down on the gas foot pedal.

Does anyone have a solution to this problem? It doesn't seem that filing the quadrant grooves deeper would make the lever stay put because of the spring pressure making it return to idle. Is there any way to reduce the tension on the main linkage spring? Is there another solution?

Appreciate input anyone can give.

Glen

It sounds like your spring at the bottom of your lever rod is weak. This put stension on the rod so it stays in place.

Thanks gunmetal blue. I didn't realize that spring was meant to put tension on the lever to hold it in position. At less than a buck at any A parts vendor, this will hopefully be a cheap and easy fix.

Cheap, but maybe not so easy fix. You have to drive the small pin out of the lever at the end of the rod, and if it's original, it been in place for 80 some years. Good Luck.

I hear ya talkin', Tom! Just spent an hour removing one bush from rear spring last Friday! It was rusted in and I had to take to it with a hacksaw. At least in my case the whole thing was off the car and accessible.

The pin at the bottom of the control rod can be pretty easy to remove.
Use a nut driver that fits over the end of the control rod and drive it upwards shearing the soft pin.
