I've got a Franklin 165-B3 (on a Stinson 108-3) engine that has some issues. My biggest question right now is the side clearance of the valve rockers. The Manual says they should be .003-.008 with .006 being ideal. If they need to be "tightened up" how do you do it? With shims or different washers? I can't find it in the manuals that I have. Anyway with the valve clearences of .040, the side clearances are way, way to much (about twice the max). Any idea are really appreciated. Bell47
