Can anyone email me a pdf copy of the continental standard maintenance practices for spark ignited piston engines, M-0????? i want the boroscope procedures sil which is no longer on the continental website, but which is apparently incorporated in M-0. of course, i can't get that, probably because i'm too cheap to pay continental for their maintenance manuals. otherwise, would be happy to get the old sil which covers compression tests and boroscope. thanks much!! tom. in lieu of those two, would like pictures of what normal valves and cylinder walls look like, and what abnormal indications look like.
