Dave you got me in a near panic!!! So I had to get out my old parts and the two motors that I have had apart have no room for two seals. The line on the outside of the block goes from the center reed and dumps into the exhaust. There is only one drilling in the lower bearing housing and excess fuel/oil that gets through the bearing goes back into the crankcase. Maybe newer motors are different but this 1956 4cylinder has only one seal!
whew dale
