1984 ezgo marathon starting issues

Be sure to remove the starter belt when checking for bearing slop, the belt tension can hold the crank in place and fool ya

Before you take it apart, remove the exhaust pipe and do another compression check. I want to make sure we aren't dealing with a plugged exhaust.

The driven clutch has no movement up and down at all.
Now hopefully this weekend I can get the motor out of the cart and start to dissect and see what I'm dealing with and what parts I need.

I hope you meant the drive clutch on the engine.

Yes that is the one I am talking about.

Jomdlcrs · 04-01-2021, 03:25 PM

Is there anything else I need to check or be aware before I tear into my cart.

Loosen exhaust and do another compression test. You want to make sure a clogged muffler isn't causing the low compression.

The muffler was new last year so I'm guessing its not plugged. I will loosen it and check just as a precaution also. Can I order parts before I tear the motor down or is it a tear down and order necessary parts.

That's a judgement call. I myself would like to see what I need before ordering. You may decide that you only want to do this one time, and be done with it. Piston, and rings are $75. The jug, and all is $235. https://www.ecartparts.com/overhaul-...ycle-gas-80-88

Either way, make sure you buy new crankshaft seals.

EDIT: I see it is advertised as a 2 port piston. Up to 88 was a single port piston. 89 started a 2 port piston. I don't believe it matters.

Thankyou I am hoping to tear into it this weekend to determine what I need. I just wasn't sure if I should get something ordered so I am not waiting forever with the way shipping has been going lately. Thankyou yet again for the info.
