Just out of curiousity, does anybody know why the balancer wasn't used 
on the gasoline engine?  My loose and pretty un-schooled understanding 
is that four-cylinder engines are inherently unbalanced at higher RPMs 
due to the differing travel distance of the connecting rods on the 
upstroke vs downstroke, or something like that, while six-cylinder 
engines are inherently balanced.  But as I think about it, it seems the 
connecting rod physics would be the same regardless of number of 
cylinders.  And either way, assuming the diesel and gas engines are both 
four-cylinder, I'd have thought they'd both have an equal need for a 
balancer.
