 I haven't tackled the 'roid. Yet. But for what it's worth, I have the 1115 and 12kw ST head on a steel frame on 1 inch rubber on a 4' 1/2 by 2' by2' red oak block (roughly 750lbs I think) on another 1 inch rubber mat on a 4 inch thick concrete floor 12' by 16'.  And still the whole building vibrates and hums. But it is almost unnoticeable  in the house.
 Anyway the Wife is happy when the power goes out, I figure that's a win and I'll take it.

I currently have 4 of the Changfoids. actually they are all of the XingDong brand. I think 3 1100's and one 1115.  The 1115 is the guinea pig for my chp system that is progress. Well it has been in progress for 5 or 6 years. 
  From my experience these are reliable, powerful and fuel efficent engines.

Hello fellow genheads! 
  Well,  what else that is not degoratory do you want to be called?
Anyway I am the (proud?) owner of a Mindong single phase syncronous generator 8kw with an s1100 engine. From what I have seen so far it looks to be pretty low hours.
This thing is circa 1999 or so and it is brushless.
  So... does anyone have a manual or even a link to one for this thing? I am pretty much flying blind here. The guy that I bought it from said he would "probably" find the manual and he would mail it to me, but I am not holding my breath.
   

Hey Cujet, Bob G and I discussed this idea a while back, but I was angling to raise exhaust temps for a pseudo-cogen system I have been working on for a few years. Unfortunately I had a bad fall in March and have been unable to pursue pretty much anything since.
 I pretty well trashed my shoulder and cracked an orbital socket. I'm 60 and don't heal so fast anymore!
   At any rate PM him, he sent me links to a few promising units IIRC.

Well, I had a 1947 John Deere "B" that used lead washers under the head stud nuts to keep water out of the valve cover and thusly the engine oil, and the studs had lasted fifty years at that point with no ill effects.  I did lose a brass pushrod tube that flooded the engine with coolant though. I was also thermosiphon and the coolant requirements were basically just clean water.
Your mileage  may vary.

You might want to check you lube oil for fuel dilution,  just sayin.
