Can you examine the control rods and look for an adjustment?
Yea.
If I were not tending the kids tonight until well past dark.
Then too lazy to head out to the garage..

Figured the "internet" knows everything so I would ask 'it'.
Cruise Control does have a friction adjustment:
Service Transmission
Adjusting Cruise Control Lever
NOTE: The cruise control lever is held in position by an adjustable friction mechanism pre-set at the factory. The amount of friction can be adjusted for the operator's preference or to accommodate normal wear.
1. Park machine safely. (See Parking Safely in the SAFETY section.)
M96061
Picture Note: Right wheel shown removed for clarity. Removal of wheel is not required.
2. Locate adjusting bolt (A) at right wheel well.
3. Turn adjusting bolt so cruise control lever moves easily forward and rearward while remaining stationary in any desired position:
キ Clockwise (+) - increases friction on lever.
キ Counterclockwise (-) - decreases friction on lever.
