I am happy to see this thread still alive! I too am the proud owner of what some tell me is the Quadra 35. Others thought it was a 70 or 79 because of the numbers stamped on it. Is there a place on this engine to find it's true identity? I have two OLD Bud Nosen big sticks to build and this engine will be going into one of these. I think there should be more support site for the Q35 or the Quadra in general on this thread. I like the bolt on starter that I have seen for this engine and the price is not that bad either. I look forward to seeing more Quadra owners post here! This could be a great support thread for us in the future. I would post pictures of mine but puting pictures here isn't that easy.Take Care, Scott
