S200 cylinder internals
Posted: Sun May 24, 2020 6:24 am
Hi guys I'm new to the forum having just found it from a link in a group I'm a regular participant in. I was recently handed an s200 to service, and after removing the cylinder ends (the rings were like hard plastic they'd been in that long)
What I shall describe as the aluminium 'plenum' at the 'block end' was rattling around loose, still in the threads but very loose with lock ring halfway down its threads. From experience I know how sensitive the s400s etc are to the firing pot extension (by association the knock open valve tension) I was wondering how much the s200s are affected by this plenum being set incorrectly.
Is there a 'standard' stand off? The thing would probably have fallen into the cylinder after much longer. I have trawled this forum using search and advanced Search, but not know the common or proper term for the tube, had no success.
Any ideas?
