Coleman Powermate 5000W Generator Help!

I got a Coleman Powermate 5000W Generator from work that was going to get tossed. The generator is about 5 years old and was used a few weeks ago when it shut off suddenly and the engine seemed to be locked up.

I was able to get the engine unfrozen with marvel magic mystery oil, made sure the valves were operating properly and the carb was clean. I put fresh gas in it and got it started. It ran for a few minutes, the idol was fluctuating drastically, then violently shut off (jumped off the dolly i had it sitting on).

Now the flywheel still moves freely (almost too easily) and there seems to be a clicking/ticking coming from the generator side when i rotate the engine. Where should I start in trying to figure out what broke?

Thanks for your help in advance!

It blew up. The connecting rod broke. Someone ran it without oil.

I have that same model genny and it should kick off if there is low or no oil.
Mine has a minor gasket leak so I will run low on oil and it'll kick off. I say minor as it's only happen to me once after 3 tanks of fuel.

Am I correct in assuming you have seporated the engine from the generator portion?
Sounds like an engine rebuild or replace if this is correct.

Cheese, thanks for the heads up and the info. It had plenty/new oil in it when the problems started but don't know what kind of abuse it had prior. I was hoping it was going to be an easy fix but i guess not!

Northern Mike, I haven't torn it apart yet. I wanted to get some info before i put too much time into the project since it really was just something to keep me busy and maybe flip it to make a little cash.

Now I know it's really not worth my time to keep messing with it.

Thanks for the help!
