Bad governor on 6.5 hp Tecumseh engine?

I have a 30 year old Toro roto-tiller with a 6.5 hp Tecumseh engine. I finally got it running but it stalls out, even with full throttle. It looks like the governor is cutting the throttle back and killing it. How do I adjust the governor?

Did you clean the carb yet?

    I have one on one of my gokarts that did the same thing. If you look at your carburetor there are 2 small screws... the one on the right is for adjusting your idle speed and the one on the left is for your air to gas ratio just play around with the one on the left a bit until it straightens out. You can email me at childress117@gmail.com if you have more questions I would be happy to help

I have one of these beasts on an old go kart, governor is broken or something, rebuilt it a couple years ago, I have picked some bolts and such off it, have a brand new carb pretty much, what exactly do you need? It was a strong running engine, but at this point it's too dangerous for the kids and I'm done dealing with it.

That's the engine number. It's a 6Hp Tecumseh. Go on ebay and buy the Troy Bilt parts manuals on CD for Horse Roto Tillers (if that's what it's on). I paid $8. Definitely worth it.

Engine starts fine however it runs fast and then slow, fast, slow all the time it's running....what is that?


It is called oscillating, The carburetor may need adjusting or it could be caused by bad fuel. Manufacturer's school this year have told us, at every school, fuel over 30 days old is considered bad gas and needs to be replaced. You may even have a throttle or governor spring that needs replacing.
Good Day.

Engine will not run at steady speed - it races, then slows, races


You sound like there is a "load" on the engine that it cannot handle. Maybe there is a problem in the generator somewhere that is dragging down the motor? A governor on a small engine like this is probably not the problem.

It could also be the exhaust side of the engine blocked. Try checking for a spark arrestor clogged up (there should be a screen inside a removable plate to clean)
