this shows a tii - but it's still the same as your carb'd model=
open the hood work yout throttle linkage thru
it's full travel and find where wiring is touching.
are you missing return springs ?
One at the fire wall
One down on the side of the pedal box seen from the outside
On the carburetor
Get lubricating......
your brake linkage will imitate your throttle soon
And as noted above - WHY DID IT STICK ?
That Can Kill You !.
Fix it TODAY.
