I just got this ezgo marathon on Craigslist for free. It was a burning man car and already had a predator 420cc. and since I got it a week ago I was going to replace the whole drive train but I was watching some videos and someone was driving the same cart, same engine and it died at a stop. I remembered the person I got it from said it was running and died at a stop and the thought it was the cvt. In the video they tore apart the cvt and it was stuck open. They cleaned it and off they went. I decided to pull the belt off mine and it fired right up. So I pulled the drive clutch and it is a comet 44c. I have no idea how to service this so I'm probably going to get a comet 40 unless someone can tell me how to get this thing apart. I'm sure glad I found the video. I was gunna junk a good 420 predator.
