EZGO Marathon Needs More Power


New Member
I am the proud new owner of a 91 EZGO Marathon that doesnt like hills. It seems to run fine on flat ground but will not even pull it's self up onto my tilting trailer. Where do I start?




Is it a 2 or 4 stroke? I thought a 91 would have a 2-stroke. Check the compression on either. If its a 4-stroke check and adjust the valves. Hows the belt look?

Belt and Compression are good. I stopped in to my local cart dealer and they had me perform a couple of tests. I took the belt off and the clutch slams closed they said that was bad and I also put the cart against a tree and the belt starts spinning without much force at all and the engine does not bog down at all.
