Secrets of Briggs Governor Speed Adjustment 

Hi, I looked up some general briggs specs and there was a range. From about 3200 to almost 3700 depending on size and application.

Glad you liked it!

Hi, black around exhaust usually means it's getting too much gas. choke may be partially closed. float may be too high. also flames could mean that exhaust valve needs to be adjusted. if exhaust valve is just slightly open during combustion you will get very hot exhaust gas leaking through. Make sure the spark plug is the correct one. There are a lot of possibilities.

Hi, the up an down is usually a lean condition in the idle circut of the carb. By now you should have had a good carb. The running rough maybe due to the choke not opening all the way. Make sure you have the sprimg on the rod going to the throttle arm on the carb. Possibly you have a worn.out cam. Take off the valve cover and check the valve adjustments. Also turn the engine over by hand, easier with spark plug removed. While turning, pay attention to the rocker arms. Watch for the valve lift. Make sure the valves are opening far enough. I ha e seen where a cam.lobe wears out and the valve will barely open.

Yes, that's what has always been in my head, used to be on the tune-up label on the older engines. Best source is probable the owners manual for the individual machine.

Really 3000/3100 is plenty 😊

Not a problem on newer engines, many don't make it 10 years.

Et c'est quoi la bonne ?

Then what would the approved method be, good sir? After thinking about it (not even seen his method yet) I can think of three ways to adjust a governor. 1. Stretch spring past plastic deformity, or cut... 2. Bend the spring tab 3. Adjust the governor linkages. He just got to his method and he decided to bend the tab, I think that's the easiest. Maybe this isn't the way a Briggs and Stratton engineer might do it, however as a normal consumer I think this video is great. He even mentioned that setting the RPMs too high would shorten the life of the mower. Great video, sir! This is good information for anyone willing to do just a little maintenance and repair on their own things, like everyone should. Thanks 😊

this method is actually to adjust the top speed, not to set the governor linkage. if the governor was apart, then that is a whole different procedure. I do actually know the difference. thanks for the comment.

My RPM stay high and for some reason it will shout off if I move throttle down a little bit, even and adjusting throttle cable. I could be bending down governor?

@@doradodelsol Hi, If you cannot control the speed as you say, then that might require a static adjustment or reset of the governor arm. this video is not for that. There are great videos of that procedure, www.youtube.com/@TarylFixesAll is my recommendation

Mixture screw was also out of adjustment

This was my first time with this type of meter. Wrapping around the wire was the key to a more consistent reading. I'm sure I will grow to trust it more with use. Most small engines will have an attachment point for the spring that can be adjusted to change top rpm.

good luck, yes that shaft should move freely when there is no linkage hooked to it.

Go to RU-vidsRU-vid's "Tyral Fixes All" / setBriggs and Stratton v-twin governor. He'll show you how to do it quickly and easily. Hope this helps.

I would concentrate more on the idle circuit of your carb. even though it may be new, they are made to run so lean, that they just don't get enough gas

@@ridingmowerking Thanx

Glad you enjoyed it!

There are actually different specs depending on application.

You are welcome!

technically it should go a specific direction. but it will filter and flow in either direction. that is how it was when I got it. considering all the other things I found wrong, it is probably backwards.

I did a video on repairing the sticking choke also,

It is correctly installed. The fuel flows from the outside through the filtering media and out from there. If installed in the other direction, you wouldn't be able to see the crap that is getting filtered because it would be inside the filtering media.

Thank you, just getting started with the video part. Hope to grow

Thank you

around 3600 is the max, a little lower is better, your connecting right will thank you.

Thank, I hope it was a help for you.

Glad it was helpful!

I'm glad you enjoyed the video! Thank you for your support!

Glad you enjoyed it

Bending the lever is really to adjust the top speed, not idle speed. There is a screw to adjust idle speed.

Yes, if you remove the plug and insert a screwdriver, and then rotate the crankshaft, you should see the piston move thr screwdriver. If the screwdriver does not move, then the liston is not connected to the crank. Likely broken connecting rod.

@@ridingmowerking It seems that in this model, the valves are behind to the spark plug. However, I think they should also move. I will open the engine to see what is in it. Thank you

The rod going to the carb may have a little rotational movement, but should not be sloppy loose in the holes on either end. There is also a spring around the rod to take out any play.

@ridingmowerking ok so pretty much much need new springs and the screw with the spring needs to adjusted and make sure all components are there.

Thank you, hope it helped

Ok, you need to make sure that the governor lever can move by hand. You should be able to move the throttle and governor lever even when engine is not running. Sounds like your governor static adjust may need to be adjusted. I do not have a video about that. Check someone like @taryl fixes all

@@ridingmowerking Thank you! Your answer is very likely. I know how to accelerate by manually moving the regulator rod, the flap at the carburetor moves correctly. On the other hand, when I operate the throttle, engine stopped, the accelerator flap hardly moves. I followed your advice, I made sure that the spring was tighter by twisting the leg a little. There is a slight improvement, in rabbit position (fast), the engine is only at about 2500 rpm or less, but it's enough to mow.

Great, you should make sure that the throttle on the carb can open all the way, look inside to makr sure it opens all the way, if not there may be something bent on the top plate keeping it from going all the way. The other reason is that the governor lever is out of adjustment.

@@ridingmowerking Thank you very much. I'm going to be satisfied with this result. I don't have full power, but it's more than enough, and at least I don't risk tightening the engine. The carburetor flap can give the maximum, but it seems to be limited by the lever. I gained a few laps, I must be at almost 2700 rpm, I don't need more. Thank you again very much.

Maybe your governor lever is loose on the shaft coming out of the engine. When it is running the governor arm will be trying to close the throttle on the carburetor. Could be that the throttle plate is sticking. I did a video about a sticking throttle on a new carb. Maybe check that out.

@@ridingmowerking thanks I’ll check it out
