>M-240       Recessed Crown Pistons (all carburator engines except
>Volkswagen Transporter 2.0 litre)

OK, something I've been meaning to ask.....  Bentley shows our USA/Canada
models as having recessed crown pistons to a depth of 11.6mm, almost 1/2".
Did we all get these low octane low compression pistons as standard for some
reason? I have always wondered how the euro wassers put out 112HP from the
identical engine, this would explain a large part of that 17HP gain, ie.
higher compression! Comments?  Seems like a nice cheap fix at rebuild time.
Unless those pesky valves get in the way!  Tim
