Default When do you change the Piston Ring ?


Hi Fellows,

What is the general opinion about the need to change thepiston ring; should that be
like gradually up to 15% drop in rpm at the same propeller-gl.plug-fuel for example,
or what is a better indicator to follow ?
Specifically I am interested in Two Stroke engines, like OS.91FX and OS-BGX but
of course all good advices are very important to me too.

Regards,
Nick</p>
