Default Onan 4.0CCK round style generator head

I am trying to convince my dad to get this 4.0cck, round style generator head, guy wants $200 I will try to offer $150 for it, supposedly the fuel pump is bad, if he gets it, I would get a universal replacement from ebay, he wants to get a gen for some remote land which would cost to much to run power to, just for 3-4 weeks of camping each year, he wants to maybe convert to propane or bi/tri fuel

what do you think of it? condition / suitability for such, I know the cck s are the "bees knees" ( im a little young to be using such a dated reference- haha)

fyi. I know its 120v only, can't think of a need for 240v , if so, a cheap autotransformer travel voltage converter (~5000w "inflated" rating) for permanent needs (eg well pump) or temporary use, (eg welder) an other gen set

cant beat a cck.. gravity feed it before you buy, make sure it has no knocks or does not smoke..

if it runs and puts out 120 volts 150 is good.. if not 100 tops.. there are always more.. a 120/240 unit is nice to have.. never know when you might need 240v

sometimes the fuel pumps stick after sitting for years with fuel in them.. the bottom of the pump comes off and you can let it soak and see if its frees up. sometimes a good tape on the side will do it.

I have a customer. That has a generator from a remote land. Five hours on it and he paid 900.00 for it. Now sits in his barn with a burned out gensection. Two years and still looking for parts.

Grab the CCK.

CCK for 'camping'? Hmm. is the 400 pound weight going to be OK?

Otherwise CCKs are great.

Watch the fuel pressure - CCK carbs want pretty low pressure...

I would pay $200.00 for old American iron and copper machine before I would spend $400.00 on a new lightweight import. Easier to find parts for a 40 year old Onan than a 2 year old no-name import.

As yellowlister mentioned, the pump may only need a cleaning. The Facet pump comes apart for cleaning and 90% of the time that is all they need.

I think all Onans are ~ 3.5 psi. Car gas pumps are at least twice that and may force open the float valve and leak gas out the carb. Fire hazzard.

Five PSI is the max you can use.

Gravity feed works. Only need tank ~ 1/2 ft above carb, putting tank ~10ft above carb make ~ 3 psi at carb. But if you run gravity feed MUST use a shut off valve or crankcase can get full of gas if/when carb valve leaks during storage.
