My other post on this disappeared so here it is again.
My engine is running a high idle after acceleration. If I don't touch the pedal it idles fine. But if I rev the engine it doesn't come back down. The return linkage for the throttle is on the spring is fine I have checked all that. When driving the car will go about 40mph without my foot on the pedal, at stop signs it sounds like I am trying to do a break stand with it.
Is there a vaccuumm that is suppose to bring it back down or something else that might have gone out on it? I only work on carb motors so I am lost on this.
Thanks for any help.
