Sounds like you need to check/adjust the governor seeing if that solves the problem, Procedure below.....

1. Loosen screw holding governor arm to governor crank.

2. Rotate throttle plate linkage from idle position to full throttle position.
Note direction of rotation of the governor arm attached to the throttle

3. Place and hold the linkage in high speed position.

4. While holding the linkage in this position, Use a approprite tool to rotate
the governor shaft until it stops in the direction noted in step 2.

5. tighten screw holding governor lever to governor crank. Torque to 35-45
in. lbs. (2.8-5.0 NM).

6. Before starting engine, Manually actuate governor linkage to check for binding.

Good Luck

Did you perform step 6 ?

It's not uncommon for carb throttle shafts to gum up from sitting and or sand getting between the shaft and carb body causing them to stick/hang up.

Double check this and all linkages then it wouldn't hurt to spray some type penitrating lube on them.

When you move the throttle control from idle to fast doe's the engine speed up really fast/quickly ?

Make sure the governor linkage is not binding anywhere.
