As a spill over from my glow days all engines mounted upright were bolted to the top of the engine bearers, yet engines mounted inverted were bolted to the underside of the engine bearers. I suppose I just followed the crowd in doing so, and switching to gassers did not pose a problem as most all were rear mounted. Now that many of the smaller gas engines are beam mounted like most all of their glow counterparts, is ther any reason why an inverted engine should not be mounted on the top of the bearers.
