1980 ezgo marathon sputter in forward but not reverse
I recently purchased a 1980 EZGO marathon and when it is is forward, it sputters and hiccups and has barely any power, but as soon as i switch the lever to reverse, the motor runs absolutely perfect. I have heard numerous answers, but wondering if anyone has had the same problem and had any luck?! Thanks for all your help!

That's usually a sign of worn crankshaft seals.

Re: 1980 ezgo marathon sputter in forward but not reverse
Thats what i have been hearing and seeing online. Just didnt make complete sense in my head how if the seals were bad, it could run perfect one direction but not the other. Would you happen to be able to give some sort of reasoning?

It spends most of its life running forward. The seals wear in a certain shape. When you run in reverse, the load changes, and they seal again.
That's my story, and I'm sticking with it. |
