engine revs when clutch is engaged

[wayfarerstranger]

why does my engine rev up when i engage the clutch while driving . it just started doing this ?? is the choke or linkage hanging up some how ?? thanx CHANCE

It could be a worn out clutch. Or it could be the clutch has been damaged by a leaking rear main seal.

What car? Fluid drive?

Might check for interference between linkage parts, down near the clutch pedal assembly & linkage, and near the gas pedal linkage under the floor.

Might be bad motor mount. Engine lifts when unloaded and pulls carb linkage.

I have actually had this same thing happen recently.

Working like a top, and then while decelerating, engage the clutch and the engine revs high and only stops when I shift into neutral... there is also some clutch chattering while this happens. I've got a plain '50 plymouth L6 and standard 3-speed in my '39 Dodge. It happened twice on a drive 3 weeks ago, and once just yesterday... no real obvious cuase or similarity between occurences.

I have the 3 speed standard transmission in my 48, and the same thing happens sometimes. If I tap the accelerator fast the idle goes down to normal. When it first started was after I hooked the engine back up after the rebuild. Thought at first it was the return spring so put a heavy one on it. That helped but the thing drove like a truck then, so put a lighter spring back on it. Then I did a little adjusting to the accelerator linkage and it helped a little. It's still there some but just never got around to playing with it again.

My motor mounts are new and tight so that has nothing to do with my problem. Check your accelerator linkage, especially if you've had it apart and put it back in. Could also be rubbing on the toe board or binding with your carpeting or rubber floor covering.
