picture please, I am trying to figure out what you mean, I have a hard time imagining a hole in the crank

Some guys at the AS site discuss this but no conclusion. This hole on the crank<pto side> is directly through the inside of the balancer. I flush the crankcase with gas and found out gas leak through this hole. It is said that the newer 3120 share crank with concrete saws. Also curious no air leaks?many husky saws have a hole in crank so sprocket bearing can be greased through crank stub, never seen one open to case inside tho
