An easy fix is to swap out the spring in the secondary clutch with a stiffer spring and replace the OEM drive belt with a heavy duty belt (G Boost and Kingzilla both make excellent belts). The fix doesn’t increase speed, just torque, which helps with hill climbing. I swapped out the secondary clutch spring in our Quiet Tech last winter, with a green spring from power equipment man .com, and have noticed a significant improvement in hill climbing.

This is a rebuilt golf course fleet cart. I know that they had to change some of the mechanical parts because if you open the governor all the way the cart can easily go over 28 mph on a flat road, but I'm starting to wonder what parts remain from it's fleet cart days. We had to have the secondary clutch replace last year, the starter replaced last month, and just yesterday, we had to have the battery replaced. The battery was from 2017, so it was the original battery in the cart. That is also when I asked mechanic to set the cart so it wouldn't go faster than 21 mph.
We've used Todd Casey from the start and have been very pleased with their service. I'll contact them to see if they think that installing a stiffer spring and a heavy duty belt will solve the.
Thank you for your suggestions.
