Need some help with go kart governor

So the actual governor setting is likely not the issue if it is running normally and not hunting. Normal governor adjustment itself should you be interested is made by adjusting the arm to WOT when the throttle shaft is as well. Usually there is an adjustable clamp on the arm. Most likely it is a throttle control or cable adjustment. I'm not sure whom actually makes the Coleman branded engine , but a couple of things that may help: Verify that the throttle arm on the carb is at wide open throttle with the machine off. There could possibly be a limiter directly in the linkage. Many of these when you remove the fuel tank, you'll see that the control bracket is elongated at the mounting screws so that the RPMs can be adjusted.

If the go pedal is pressed fully then it can travel to WOT. It’s just a very low rpm when the governor pulls it back. I have no clue what the governor arm looks like below the gas tank. I guess I’m going to have to remove it and have a look for different settings. Engine runs smooth right now, there is no hunting.

You might be able to adjust the governor at the point where the rod connects to the control arm coming out of the crankcase. I had to do this on a motor where the link got bent while I was working on it. A lot of times these are just a screw clamping a bracket onto a round shaft. So loosen the screw, turn the shaft one way a little bit, re-tighten and try it. If it gets worse, try turning it the other way. Then it should be just trial and error to get what you want. If you have observed which way it turns when activating, it might save you the guessing which way to move it, but not a big deal.
Oh yeah - mark both parts with a fine sharpie before you loosen anything just in case...

Good point. If it's like the governor on the Kawasaki engine I was working on this summer, you want to:
1. Loosen the bolt that clamps the lever to the shaft.
2. Rotate the shaft to its maximum position.
3. Adjust the throttle to its maximum position.
4. Retighten the bolt that clamps the lever to the shaft.
That way maximum position on the governor is at maximum position on the throttle.
Oh come on, that takes all the fun out of it.

Thanks for the tips. I really didn’t want to remove the gas tank to adjust this thing. But it looks like I’m going to have to. Basically all the linkage is under there.

This thought has also crossed my mind. However the reason for clutch slippage would be due to lack of higher rpms (or oil on the plate, verified the clutch is clean and in good condition). I’ve looked at new clutches and they’re in the $40 range. I do not see any specs for them is the problem I’m finding. I’ve seen a lot of people recommend the MaxTorque brand.

What I’m thinking of doing is making a hand throttle directly to the carb that bypasses the governor for him to grab for the extra umph to get up the hills. Sort of the same concept of a nitrous button. I can push him up the hill with one finger pushing right now while he has it floored so all he needs is just a quick spurt to get moving. This would allow the go kart to function as designed for 99% of the rides.
