Warner Super Scarab piston types

[b guest]

'It seems little information is available as to the different styles of
pistons that were available in the past. Is it possible some one has
that information and can accurately describe the three or four styles
that were used in the original Super Scarab 145 HP. engine. We
understand they were all the same dimensions but some were three ring,
some were four ring, some had a slightly concave top with a slope of
about a half inch width all around the circumference but flat otherwise.
Some were rough cast on the inside with a number of webs. Others were
smooth cast with just the piston pin web. And of course they all have
different weights. So if any of you Warner Super Scarab owners have any
information we would appreciate your sharing it with us. Thanks Bruce'
