I just purchased a Ariens 11526DLE.(11.5HP, 26", DLE), delivery is tomorrow.  I noticed in product literature the 9.25HP and 11.5HP Tecumsuh motors have same displacement.  I believe they're 318cc.   Anyone know the technical differences between the two motors and Tecumsuh achieves the additional 2.5HP?

My appologies if I misinterpreted your reponse or seemed unnecessarily strong in my comments.  I understand your points and I think we're in full agreement.  The tone of my comments were no doubt influenced by my frustration in seeking a simple clarification from these manufacturers.  This is a new experience for me, forgive me.  I really appreciate your comments, experience in this area and now your patience.  Bear with me and thanks again.
