I have a 29' 45 inch motor and made the decision to buy new flywheels from Truett and Osborn ... I took various advice before deciding on this route and I'm very happy with the quality of the T and O machining .... Somewhere during my various search for advice I was informed, by more than one person, (I can't recall exactly who) that these wheels need a small amount of machining on the thrust faces .... can anyone on the forum give me help with this one .....
