Jim,
though I'm unfamiliar with all CS engines except the Silver Swallow and Jin Shang (If both were made by what later became CS...).
By reputation, and a few mag articles, CS has made some very high performance engines, but QC may be a bit spotty. By high performance, I mean extreme high RPM. One article I recall dealt with fitting a 1/2A or .06 (metric half-A: 1cc) for a proto speed model.
If the .21 diesel CS is a basic sport engine like the SS and Jin-Shang, those at least worked well and reliably -- the 21 might, also.
However, if it were a useful, easy to set up engine, I suspect someone would have made that known by now.
Personally, I'd be a bit leery -- but then I can afford to be, with more than a lifetime's supply of strong 15s and 19s already on hand.
Best luck!.. and if you do try it, and find it good, let us know?
