![]() ![]() The governor and the throttle are connected together by a spring, called the governor spring and the strength of this spring determines how fast the engine spins. Working against it is the lever you move which I will call the throttle. The faster the engine spins, the harder it closes down the butterfly, How much it closes the butterfly is determined by how fast the engine is spinning. The governor slows the engine down by closing the throttle ( which from here on in I will call the butterfly to avoid confusion ) Horizontal shaft engine, you would loosen the nut on the governor armĪnd push the governor arm down, clockwise.The thing you are having trouble with is the governor. To adjust the governor on a Briggs and Stratton Hold the lever and clamp in this position while tightening the screw. Push the governor lever connected to the throttle to the wide open throttle position. Rotate the clamp in a direction that will force the throttle shaft open and allow the governor follower arm to rest on the governor spool. With the engine stopped, loosen the screw holding the governor clamp on the governor lever. ![]() If the air flow is blocked it can over speed the engine. The governor spring is preciselyĬalibrated for an engine that has full air flow going through Very important to keep the cooling fins clean so the proper amount Problem with air vane governors is debris sometimes collects in the system blocking air flow. This type of system uses theĪir flowing through the engine to operate a vane back and forthĪgainst a spring, just like the mechanical governor does. Sometimes you may have to change governor Repair manual for the engine you have and see if it has a way ofĪdjusting sensitivity. Governor spring to a hole further away from the governor shaft you Several holes in the arm to change sensitivity. ![]() Quickly and over compensates for the speed. Have checked the adjustments I talked about above, then you may haveĪ governor that is set too sensitive. Governor, but a partially plugged carburetor, usually a plugged Most of the time this is not the problem of the The other problem that often occurs is governor hunting or The internal parts checked inside the motor or recheck the static Speeds or has no push toward idle, you probably will need to have This test is with the governor spring removed. Push the arm back toward idle if working properly. Governor lever with your finger to open the throttle and it should Refer to theĮngine repair manual for exact adjustment procedures.Īfter you have made the above check, restart the engine and see if the Make sure the throttle movesįrom idle to full open freely after making the adjustment. If it goes clockwise, then loosen theĬlamp screw and with the throttle wide open turn the shaft all the The best way toĭo this is to move the throttle from idle to full open and note the Has been removed between the spindle and carburetor. Is operating freely and the spring is not damaged or stretched.Īlso, check the governor static adjustment to see that all free play Inspection of the governor linkage and spring before trying to solveĮither of these problems. Most complaints about governors fall into two categories: To adjust the mechanical governor on Briggs and Stratton and Tecumseh Engines.įirst, let's understand a little more about governors and why they may Over speeding is something that needs to be takenĬare of immediately, because it can be a real hazard with metalĬoming loose at high speed. Evenįor a short period of time it can cause catastrophic failures, like blowing the magneto magnet into 100's of little pieces. Run an engine over speed, especially without a load attached to it. IfĮngine speed is not controlled, the engine will destroy itself. Improperly adjusted governor can shorten your engine's life. One of the most important parts of your engine is the engine governor. In the event that they do need adjusted, here is how to do Generally Governors should never need to be adjusted, unless the governor arm ![]()
