Hi, I'm working on my 503 engine. I need to replace 6 protection caps that are cracked. I've searched the Rotax manual, forum, and found nothing. Is there concerns while I replace these caps? I don't want to mess up the timing.
The Mir diamond mine in Siberia is the deepest ‘proper’ man-made hole. It’s 525m deep and 1,200m across. There’s a no-fly zone above it because the downdraft created by the hole had caused several helicopters to crash.
