doyle 1950 Would forge right into that shim adjustment on those mains,peel the pan off ,let it drip a day or two,then adjust them all rods and mains. A careful job there will last you a long time. They used to sometimes push them to get running,that is a little too tight though !! Doyle 1950 Another test for main noise not mentioned yet is if you let up on it at road speed vacuum will pull the crank up into the block and stop the knocking,like on a steep hill. Downhill that is
