What is the factory tolerance on throttle shaft for the NH carburetor?
Are you making the shafts os or standard? I don't know the answer to your question just wondering. Loose enough to turn but not so tight to stick!
Mark, The shafts I made today are standard & ported.
I have several NH's that will need shimming or oversize shafts.
Most carbs need os shafts that's why I asked. It's one of those parts that could stand to be made for wear. The Drive shaft bushings are another one of those. It would be great if the suppliers sold for under sized drive shafts.
Thank you for the "how to do it" lesson!
