When I bought the cart, it was loud and basically had no power especially going up hill. I replaced the drive clutch and belt. Cart got quiet and seemed like it had a little more power. Still lost power when going up hill. I have drove carts all my life and I notice that it doesnt feel like it "shifts down" like othe carts do when going up hill.Noticed that the motor mounts were jacked up so I replaced them also. Still does not have the power it should. I took the cover off the secondary clutch and sprayed it with WD 40. I am not sure if it is a carb issue or what. I am going to use some carb cleaner on it this week and I did change the fuel filter. All I know is that if I keep going at this rate, everything is going to be new. Any advice or ideas would be appreciated. Thanks
