I’m not clear what the maual means relative to valve stem diameter
This shows valve stem diameter at 5/16, or .3125 then there are two figures, -.0025 and -.0035. I assume this is the tolerance for wear, is that correct? Seems strange to have two numbers in there.
It’s a bit of an academic question perhaps since my stems are all between .309 and .310, and I’m already in there, but I would like to understand it when the machinist gives me the low-down…
