Hello all! I just (finally) figured out how to post to this forum. I'm building up a very stock S1-S. The only real departure is the use of an angle valve engine. I have a really nice HIO-360-A1A core but it has the crank with the holes in the prop flange. I want to get a solid flange non-counter-weighted crank for it. Can someone tell me what the acceptable part number(s) for the crank might be? Or maybe tell me what source documents I would use to determine the part number? I've already talked to Lycoming and they referred me to their document SSP-110-01 but I'm having some problems with that. Any help sure would be appreciated! Thanks! Kim Kovach
