2002 ezgo txt gas- acceleration problem

[Woswald]

Just purchased a 2002 txt gas cart. It starts and runs great. The issue I am having is that there is no gradual acceleration. I can’t get the cart to run slow or mid range speed. It is either too speed or it is jerky when trying to go at slower speeds.
I checked the throttle linkage, the engine will rev before any of the cables that link to the governor move at all.
Any suggestions would be greatly appreciated.
