I have an stihl 036 that I rebuilt. It has a problem every time I tighten down the clutch side the crank/flywheel become almost impossible to move by hand. It's only after I put the clutch on though. I'm positive I have it installed in the correct order. Metal Washer then metal shaft that goes on the crankshaft, oiler, worm gear, clutch plate then clutch. Anybody ever have this problem? Also I'm not over tightening. Suggestions thank you
