Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!
Is there a speed sensor on the end of the drive motor? Unplug the sensor and see if it makes any difference in drive speed. Next , does the cart have the OBC? Try a reset of the OBC. Link below to see reset procedure,
If no change , the MCOR, motor control output regulator(foot switch) is bad.
I see question is still open, did you find problem?
