I have an 86 Toyota Pickup with a 22r. Last night I was returning home from the store, I slowed down for a stop sign, put in the clutch and the motor RPMs increased. I let out the clutch and it accelerated very quickly without me touching the gas pedal. I was thinking that the linkage on the carb was stuck, but upon inspection, the linkage was fine. I have cleaned it and done everything else I can think of. I did notice that the boot on the accelerator pump was torn, but I do not know if that could have anything to do with it.

I don't have a tach, but I am guessing that I was pretty close to redlining the engine.

When I was driving home after the problem started, I was doing 50 mph, without touching the pedal. (unwanted cruise control). I could downshift to lower my speeds and it wasn;t too bad, but obviously something is wrong. It ran fine as long as it had a load on the moter (clutch engaged). I rebuilt the carb about two years ago and it has been fine. I suppose I could rebuild it again, but don't really want to if not necessary. I crank it, and it starts fine, then begins to accelerate again after a second or two.

I figure some of the carb experts on the board might have an idea of what sort of problem this is. I am sure it is obvious, but not to me.
