im currently obsessed with these briggs engines.
i know there's two 46ci engines one with a longer stroke and one with a large bore (super rare, i wish i had one)
and then there's 40 and 42 ci engines as well.
my question is are the crankshaft ends where they sit in the block and pan (bottom half of crankcase that unbolts) the same, could they be placed in any opposed twin engines, if not which ones will fit which.
my second question is if anyone has a few cranks on hand, what are the throw offsets (distance between center nose and crank shaft pins (where the connecting rods connect.)
thanks,
