Small Engines (Lawn Mowers, etc.): governor lever on b&s 12hp, throttle linkage, throttle plate


Question
I have just recently rebuilt a b&s 12hp model 281707 type 0411. the engine only had approx. 25 hours but had been sitting for many many years. I would like to know how to properly adjust the governor crank position with the governor lever. The engine only wants to barely run or run wide open and I think this may be where my problem lies. Thanks.

Answer
1) Loosen screw holding governor lever to governor crank.
2) Rotate throttle plate linkage from idle position to wide open position.  Note direction of rotation of the governor arm attatched to the throttle linkage.
3) Place and hold the linkage in high speed position.
4) While holding the linkage in this position, rotate the governor shaft until it stops in the direction noted in step 2.
5) Tighten screw holding the governor lever to governor crank.  Torque 35-45 inch pounds.
6)  Before starting engine, manually actuate governor linkage to check for binding.

Let me know if you have any other questions.
