They are Mechanical and Pneumatic. Had one engine, before I learned to block everything, that shot a mouse out the exhaust along with part of it's nest. I've never liked the full throttle to get choke and starting at full throttle or close to it. Typically it where the intake elbow meets the block. To verify this, disconnect the governor linkage and idle the engine. Also notice the governor lever is also moving in the same direction specifically from idle to wide open.

What Is the Way to Adjust a Briggs & Stratton Governor?

There are many variables that could be causing your problem, so the more information you can give me, the better I can help you out. To adjust the governor, a wrench and a clamp tool is required. Thanks again for all of the suggestions, I can not imagine working on stuff without forums like this. The big problem with air vane governors is debris sometimes collects in the system blocking air flow. If there is no movement it could be that the flyweights are stuck or the little thimble is frozen on the shaft it rides on.

Briggs and Stratton Governor set up and adjustment

briggs and stratton governor spring adjustment

The top engine speed is varied by increasing the spring force to run faster or decreasing the force to run slower. I have a 326437 and that's just what I needed more info on. I just hope it's not an internal governor problem. When I contacted the company, they were no help. Governors are on every single air cooled engine, from lawn mowers and edgers to generators and one man augers. Problem now is that the trottle never close so i get a low idle. I put the governor back together according to shop manual.

How does a small engine governor work?

I tried their help line and all I got was a reply that said that they would sell me parts but they would not provide tech help. Use caution when using this solution as it is very strong. If the governor doesn't work, it's blown. If the engine is running at a reasonable speed at no load and the governor is stuck you could expect the engine to bog down and almost quit when a load is applied because the governor can't advance the throttle to maintain constant speed in the face of the increasing load. One of the most important parts of your engine is the engine governor.

27 hp Briggs and Stratton governor/idle/spring issue

briggs and stratton governor spring adjustment

I didn't notice that spring when I took off the carb for cleaning, but I just assumed that the top hooked around the throttle pivot sticking out the back of the carburetor and it seems to work okay. Over speeding is something that needs to be taken care of immediately, because it can be a real hazard with metal coming loose at high speed. When you say it dies, does it at least try to stay running or does it act like the key was turned off. Depending on your speed setting on the dashboard throttle control, there will be some resistance from the governor spring s , but basically the linkage should not bind or hang in any way. If the engine doesn't start and immediately pin the throttle to idle, you have a failed governor gear. Move the governor arm so that it stretches the spring as much as it can. When I do get it to run smoothly, it dies after I use it for a while.

The choke lever is a small, bent arm made from metal or plastic that opens and closes the throttle in response to an adjustment of the throttle lever on the handle of the machine. I should have taken a pic of it before tearing it down : thanks! I had the coils from my old motor, so I used one of those. A governor does the job for you by detecting changes in the load and adjusting the throttle to compensate. The governor arm does not appear to move can move it manually and engine will accelerate How can i fix this???? I have not replaced the governor linkage and the spring on it is missing. Let me know your results. Thanks, Doc These engines will run fine on one cylinder, until actually loaded down.

Could it be something has happened to the governor inside the engine. Now notice which way your moving the throttle linkage as if your moving the throttle from idle to wide open. Let us know how it goes. I just got finished putting a new 44Q777 Briggs 27 horse professional v twin in a dixie chopper zero turn that had a kohler. I am interested to hear the results of adjusting them counter clockwise, because that will hold the throttle wide open on an engine like this. As the load lessens and engine speed increases. See your owner's manual for cleaning of cooling fins as this is very important for proper operation.

I have not yet cranked it. If it's the cable, adjust it to let the throttle butterfly on the carb rest on the idle set screw stop on the carb body. Takes about an hour total, to fix. Pneumatic governors are powered by an external air vane, while mechanical governors are run by a gear and spool assembly inside the engine. Once the governor gear grenades, you're done racing, and the engine has to be removed, the case halves split, and the gear replaced.

The speed-sensing device on a pneumatic governor is a movable air vane, made of metal or plastic. As you accelerate it, you should feel the governor arm trying to close the throttle. Living in Sweden these 23D motors are rare over here but my father in law has one 8Hp on a small boat which didn't run. Thanks again, Doc Just pop a gov gear into it, check that stud, as wwxx suggested and you'll be good. To set the governor at its proper position, loosen the screw on the governor arm so the governor arm will turn on the governor shaft. My guess is that the governor is not working. Step 3: Turn the governor shaft After opening the plate completely, take a wrench and turn the governor shaft in the direction of the governor arm.
