I’m really stuck with an issue with my gas EZGO golf cart. It starts up okay, but for some reason, it just won’t rev up enough to get moving. It’s like it’s stuck in slow motion. I’ve tried a few things, but nothing’s working. It’s really putting a damper on my golfing weekends. Has anyone else had this issue? I’m desperate for any tips or advice you might have!
Response
I do get where you’re coming from! I had a similar issue with my EZGO. In my case, it was a clogged muffler. After a thorough cleaning, it was as good as new. Maybe give that a shot? Good luck!

- What I Did: Upgraded the ignition system to a High Energy Ignition (HEI) for a more robust and reliable spark.
- Outcome: Significantly improved ignition efficiency, resolving the revving issue.
- Personal Experience: This upgrade brought new life to the cart’s engine performance.
- Steps:
- Purchase a compatible HEI conversion kit.
- Disconnect the old ignition system, taking note of all connections.
- Install the HEI components, following the kit’s instructions.
- Reconnect the power and test the cart for improved ignition and overall performance.
- Expert Tip: An HEI conversion can be a cost-effective way to revitalize an older cart’s ignition system, leading to better fuel efficiency and engine response.
- Check Timing Belt and Cam Gear
- What I Did: Inspected the timing belt and cam gear for proper alignment and wear.
- Outcome: Corrected the timing issue, allowing the engine to rev up correctly.
- Personal Experience: Realized the critical role of timing in engine performance.
- Steps:
- Access the timing belt and cam gear, often located behind a cover on the engine.
- Check the alignment of timing marks on both the cam and crank gears.
- Adjust or replace the timing belt if it’s worn or misaligned.
- Reassemble and test the engine for improved performance.
- Expert Tip: Timing issues can be subtle but have a significant impact. Regular inspection of the timing belt and gears is essential for maintaining engine health.
