Yamaha G16 cuts out at full throttle – seeking solutions!

My Yamaha G16 has been a reliable cart for years, but recently it started cutting out whenever I hit full throttle. It’s really frustrating, especially when I’m trying to navigate my way around the golf course or just enjoy a ride around the neighborhood. Has anyone else experienced this? I’m desperate for some advice or solutions that have worked for others.

Response

I had similar problems with my brothers G16 cart. After a bit of tinkering, I found that cleaning the carburetor thoroughly made a huge difference. It might be worth a shot for you too.
