Question G16 Jumpy Throttle

I have a 98 G16 that I just got a couple weeks ago. First thing I noticed was the throttle is really jumpy with anything under half throttle. I have since turned up the governor which I can't say hurt or helped the issue. It is just somewhat difficult to drive as it doesn't want to go smoothly unless it is at least half way to the floor. Any suggestions on things to check or adjust?

Make sure clutches are operating smoothly might need a good cleaning and lubed

It would help greatly if you could determine whether the "jumpiness" was caused by engine misfire, or poorly engaging clutches. If the former, you may have to disassemble and clean the carb, as there maybe something clogging the idle and off idle circuits. It's probably not ignition related if it runs fine at WOT or close.

If it's a mechanical jumpiness (engine seems to run at a constant speed but the cart lurches and bucks), then you need to check the clutches. Make sure the sheeves are smooth on both primary and secondary, the belt is not ragged, and the zerks are properly lubed so the the sheeves can move smoothly in and out on the shaft.

Is this a problem of "cart runs too fast with little throttle application" doesn't give you much low speed control when pedal barely pressed enough to crank engine? Could just be a cable adjustment at the governor.

OK so I have greased the primary clutch as noted above but where is the grease zerk for the driven clutch?

I know it is really late but just in case someone needs this help down the road, I took the advice and adjusted the throttle cable at the governor and made a world of difference. Checked the butterfly at the carb and it wasn't fully closing and was getting to WOT at about 1/3 pedal so backed it out a bit and now it is much easier to drive. Thanks for everyones input!

Lot of people think that makes them faster. You should have no throttle opening just after the pedal switch starts it, then you will have no problems. You can also try setting the carb to idle just faster than the starter that can help them start quicker, if your carb has an idle mix screw I don't know if all do. That helps get a slow idle.
