Ive never seen bottom end failures on work saws, but Cliff mentioned he used to have crank bearing failures on the saws run at 50 to 1 in the woods.  Didn't Bell do a test on mix ratios from 16 to 40-1 and found the richer mix made more hp? 


I remember they had failures in short time in the cranks and or bearings in those solo 681's they got.
