2012 Yamaha Drive, jumpy acceleration at low speed.

[Dogmike]

Hello there. I am having issues on my 12 yamaha drive at low speeds. It seems there is a sweet spot that I can sometimes hit with the pedal but most of the time its jumpy at low speed and when first taking off. I'm not sure if this is a carb adjustment or cable adjustment. The clutches are working smoothly so I dont think the problem is there. I can barely press the pedal and the motor turns over, when I press slightly more is when the jumpy acceleration starts. Once I am moving I have no issues at all. Any help would be appreciated. (I'm new to the Yamaha's)
Thanks in advance.

Check your accelerator cable that goes from the pedal to the governor on the transaxle. Make sure it's not kinked or bent weird. Also follow the cable from the governor to the carb and check it too. If you can spray some WD40 in the cable and work the cable back and forth. If it's rusty in there at all the cable will stick and cause bad throttle action.

Check the throttle blade at the carb to see if its closing all the way. Disconnect the cable, back the very top adjuster screw off until theres a gap, then tighten it until it "just touches, but does not at all open" the throttle. Reconnect the cable. Chech that theres some slack in the cable (this part is just as important as the carb adjust part).

Thanks for the information from both of you. I think I'll check the cables first just to make sure everything is moving freely. I had the carb off a month ago or so to clean it (found sand in bottom of bowl). With the carb off, the butterfly closes all the way. If I still have issues after checking the cables I will pull the carb off again and check it out. When I find out what the problem was I'll let you guys know.

I am going to throw something at the wall and see if it sticks. When I first got my cart it came with a worn out belt. Without knowing better I bought an after market belt and when taking off it jumped and deposited rubber on the face of the clutches. I bought an OEM belt and cleaned the face of the clutches with mineral spirits and the problem was solved.
