I hope SS is reading all this, it might shake his faith in the reliability of American engines.
I know its up to us to try to avoid cylinder cracking, but I believe the narrow envelope for avoiding cracking is inherently bad design.
I confess to feeling a traitor to my engines when buzzing around on one just to prove it can be done for the annual revalidation.
Perhaps I will follow others' example and book a school twin for that day in future.
