Well you certainly are not getting muc sympathy for your plight are you? I agree they did more than justified by the evidence. I have always found that Horizon went that extra mile when it came to Customer Support and I think they have indeed bent over backwards. I would say that the weight of the pushrod and inertia involved probably busted acouple of teeth off the intermediate gear and locked it up. Too many variables to guarantee against. My vote goes to Horizon.
