Default Old CCK Lives! What Now?

This 5000 watt CCK is in an old motorhome on a vacant property I am renovating. Thanks to some guidance I received here I solved the spark problem and like magic it fired right up after five years sitting.

Given the mileage on the RV (29K) this probably has VERY low hours.

Everything looks pristine under the covers, oil looks decent.

I need to start using this thing now to renovate the property. I changed the plugs and filed the points. Everything else is original.

Anything else I should do ? Additives? Carb cleaner?

Change the oil! Regardless of what it looks like.. clean the slip rings and check that all the brushes move free in there slots..

Load test it and check the hertz and volts at no load and half, and full load.. let it run for a few hours and maybe change the oil again since it's been sitting so long..

Should not drop under 112v under full load.. 128 volts unloaded..

You have a great generator that nothing can compare to in that size.. that runs on gasoline... except maybe a old kohler

Most likely a very low hour unit. Do as yellowlister told you. Make sure the brushes are free in the guides. If they stick they can do some costly damage. The main thing is to use it. Letting it sit is not saving it. You have one of the best generators out there. Take care of it your great grand kids will enjoy it.

thanks.

Can you give me a hint about the brushes? What am i looking for, how do i access them?

I didn't have a meter with me when i fired it up today (before I read the suggestions here)

It drove the coach roof air with no hiccup.

How much oil should it take? There does no seem to be easy access to a bung so I'm thinking I will pump it it out of the filler cap.

There is a band that covers the back section. Under it are the brushes. The ones towards the engine are the start brushes. The ones towards the rear are the AC brushes. You should be able to pull on them. They should snap back when you let go. I would think there is nothing wrong with them. Being a low hour unit.

It will hold around 4 quarts. Do not check it while running. Only while shut down.

Went back and fired it up again today.

Not knowing what I'm doing i turned the adjustment screw on the points and timed it by ear. (that is timing, right?)

Ran rough for several minutes before smoothing out. Still had a slight wobble in the engine, barely perceptable, is that the governor?

Then i fired up the roof air. Given the outside temp i'm thinking the compressor did not come on but the probable 8 amps or so. With that running i had 121VAC

Wow this machine is incredible.

I ran a 70 foot cord to the house and into the drier outlet (yes, i probably know what i'm doing)

THen I threw the switch, the motor made the slightest grunt as the governor took the load.

In the house i found two window units running (house had been closed in the summer)

I love this machine.


One more question- the electric choke refused to open. The gen ran for a while then died after it wared up. I held the choke open with a block of wood and let it run.

After a half hour or so i was able to remove the block. What's going on?

Pull a spark plug and see how its burning. If its black its running rich. If its a nice tan brown color its burning well. I would guess its running rich with the choke being closed. I dont know what choke it has on it but it could have been assembled wrong or no power to it ?

Thanks. I think i was not clear.

Up to now the electric choke was not connected. I was starting by choking it with my hand.

Today, having fixed everything else i fixed the connection to the auto-choke.

It closed when i powered the engine, the gen ran great until it warmed then the choke refused ot open.

I pulled the wire but it stayed closed so i blocked it open.

After it ran a while i puled obstacle out and the choke remained opened.

No one has messed with the choke at all. So this is a newly acquired problem. In the past when this was run the auto choke worked fine.

Check the resistance of the choke element to ground. You may need to clean any rust or corrosion on the choke element plate so it gets a good ground connection.
