engine is running with the crankshaft forward all the way, and you
push the clutch pedal in (which pushes the crankshaft toward the
rear of the car) the gear on the crankshaft (which turns the
distributer gear) moves toward the rear and bumps the timing gear a
few degrees, which in turn, turns the rotor in the distributer an
equal amount. You can see this on an old motor with excessive
endplay by watching the distributer rotor move when you push in and
out on the pulley.

Just pushing in the clutch and letting it out doesn't do anything put
if you put it in gear and let it out, the rpm's increase all by
itself. This allows you to actually take off without using the gas
pedal but then it's like the pedal pops back to where it should be
and the rpm's go back to normal.

?!?

If it happens at idle this suggestion is no good, but if it only
happens when you shift gears, perhaps your manifold is loose,
causing the carb to rock backwards and pull the throttle arm each
time you let the clutch out after shifting? Just an off-the-wall
thought that came to mind when reading your post. Good Luck,

rpm's when I let out the clutch. It was suggested to check and see
if the accelerator cable is wrapped around or near the clutch cable,
plus other suggestions. I followed the suggetions to no avail. It
only happens when the car is in gear. After a few seconds the rpm's
drop and I can go about my business, but change gears and it happens
all over again. I only notice the most in 1st and 2nd gears. Any
other ideas?????
