Chang-chai and ST head, deal? Or no deal?
dkmc:
It ain't pretty...
Found this, seller was asking $600 said he'd take $550. I saw it run, started right up with the electric starter.
He knows nothing about the ST head, wires are disconnected. Data tag is unreadable except for 2000 which may
be the year built. Is there a stamped model/ serial number someplace?
Worth the money?

It looks like an ST-7.5 head. It looks like it’s been outdoors for some time. It will probably need new bearings and brushes. I would see if the generator head works.
If it’s been rained and snowed on the generator head probably needs to be rewound. That’s if the rotor and stator laminates are still good.
Might be cheaper to purchase a replacement ST head.
I think $550.00 is too much of an asking price. It seems like it was not taken care of very well.
I believe your in the North East. Check for freeze cracks in the block around the cylinder.
dkmc:
Also meant to ask, is there a manual available online for these engines?

i wouldn't give any value for the st head, it is an st8 which is really an st7.5
if it works or can be made to work economically then it is a bonus, but don't add value for it in the purchase price.
the frame and pulley maybe 50 bucks
the engine? hmmmm, given the current market and there really aren't any available
for sale, at least yet, that value is between the buyer and seller.
if it were me and i really was in need of the unit, i would offer no more than 500 cash money, "if" the engine started up from cold, and not after having been running before you got there.
if it started from cold, i would maybe go 500 for the unit, if it was warm when you got there you really have no idea what he had to do to get it running. he may have needed to give it a half can of ether to get it going.
a hard starting engine is going to need work, and that takes the value down to maybe about half his asking or around 250 bucks.
as for a manual, i am not sure about an online manual, but i think i have one i can copy and send you, just would take a bit to find it. i have several, just finding one is all we need.

+1 for hwew' comment about checking for freeze cracks, fill it with water and check for leaks, cracks etc.
i am also concerned about the condition of the aircleaner in the picture, why is it all apart? how long has it been open? has it been stored under cover? looks like it has been fending for itself out in the elements, and if the aircleaner has been left open? dirt? water, bugs, leaves, did i say dirt and water?
if the intake valve was closed then the cylinder was probably saved, but how much rust on the valve stem, and when he rolled it over, how much dirt and crap was ingested on the first startup.
the more i look at it, and the apparent poor condition from the elements, someone really didn't care much for this generator, and a dead generator really isn't a generator is it?
500 bucks is a gamble that i wouldn't take, not unless i was prepared to spend the time, and money to go through and overhaul the engine, and maybe also replace the generator head, and even then the frame is a light duty portable designed for intermittent use. probably just what this poor thing did, run for several hours of power outage, then left to fend for itself, wash/rinse/repeat until one day it either didn't want to start (probably when the aircleaner was taken apart) or the generator quit (probably when the control box was disassembled. then they just went for a beer and a trip to town to buy a cheap gas generator and this thing was left where it sat.
i bet i am more right than wrong on this one, and the more i think about it, 250 bucks is a good cash offer.
he ain't gonna get more from anyone else! there aren't that many of us out their looking for these things, and even fewer than are looking that have the ability to make it work again.
offer him 250 cash, leave your number and walk away, tell him you have to go look at another one that has been kept under cover and works.
he will either stop you and take the offer, or he will be calling you shortly.
btw, take you wife with you, start with small talk, ask if he has a wife, get her involved!
to most wives that rusty pos? hell ya babe we are gonna take his 250 bucks!
