I have restored 5 or 6 M S 80 (one was a Wayne 80), the doors on all but two would close and fit tight on both sides and across the top. But on the two the very lower end of the door fits good, the top half from belt high and across above the window, the door does not suck down tight against the pump body even with the locking levers locked. Is there anything that can be adjusted to get these doors to have a better sealed fit when closed?
