The engine is a 21 HP B&S V-Twin Intek. The engine was idling higher than it should, so I finally adjusted the governor, doing the clockwise adjustments while holding the throttle wide open. Now the **** thing wants to run as fast as it can, scared the sh*t out of me when I started it. I know it’s adjusted the way these get adjusted but why on earth would it suddenly now wanting to be run so fast? Does the governor inside these engines somehow go bad? It wasn’t running this fast until I screwed with it, and I’ve watched a couple YouTube videos to be sure I was doing it correctly.

I often tell people to try to stay away from ever adjust the governor on these engines. It is usually not necessary and I've seen people get into real trouble and damage thanks. In the original situation where the running speed was either too fast or too slow you didn't need to loosen the pinch clamp on the governor to increase the speed you only have to bend the tab that the spring attaches to that pulls on the governor arm. Watch the video I'm sure it will tell you the proper way to do it as he does good videos. I just hate most YouTube videos because most people do things the wrong way or the hard way. He is very good though.
I have had more than a handful of Briggs & Stratton twins with exploded governor's. When they are just a properly and running the governor will have no auto action that is how you will know. Whatever speed you set the engine at t will not be able to maintain the speed. When you engage the blades it will bog down excessively because the governor will not be able to move and adjust the speed on his own.

I’ve had to adjust the governor before because all of a sudden it took off on high speed in September. I watched videos again to be sure I was doing it right again because of not being able to get it to slow down. And I agree, Taryl is very informative on all things small engine.

Yeah, I’m done with it. I bypassed it, I don’t feel like taking the engine off of the tractor and apart right now. I attempted it a couple of times and each time it wanted to run wide open.

You can barely get by enough to cut grass if you wire the throttle in a fixed position to where it's got just enough to cut grass with the blades engaged BUT don't turn the blades off and let the engine keep running and make sure you engage the blades right after you start the engine otherwise you will severely over rev the engine. I had a neighbor with a 21 or 22 intek that the governor went out on it and we wired it this way so he could finish cutting the grass right before we fixed it. Just don't let it rev too high or you will SNAP a rod od or have one of the rocker arms jump off or bend a push rod. Also, keep the oil at the full mark which is important for Intex all the time as they don't tolerate being low on oil and will snap a connecting rod in a heartbeat but especially if you might be rubbing it higher than it should be. It is never a good idea to allow an engine to over rev especially not a twin intek.
I've done a good number of those and it does suck to have to take the engine off and take the bottom cover off just to fix a stupid $18 part that they should make better in the first place. Normally they come out in eight or nine pieces. I can usually do one now in about an hour and 5 minutes to an hour and 10 minutes if I'm in a hurry but I rarely get in a big hurry.

Thanks for the concern but that won’t be an issue. I didn’t describe very well what I had done. This isn’t used as a grass cutter anymore, I have a redneck setup done to it. I have a return spring and foot throttle ran to run the tractor now to be sure it doesn’t over rev. I used two hose clamps drilled out and took a bed frame spring and twisted it to make it work around the throttle lever and to the clamps.

I tried to hook to the throttle using the dash control as well but yeah, it’s too touchy and can’t get a perfect engine speed using that while using the dash control. The foot throttle worked perfect for it.

You would be surprised, it’s not a lot of foot work. It works pretty well. Now if I still used the engine to power a mower deck then it’d be a different story.
