Hi Tom, engine really looks nice. For screws that will not stay in I use purple Loctite, their no. 222. It is low strength so you can get them out later. If threads are gone so screw will not tighten I use helicoils. Not available in many sizes including 4-36, but it is available in some pitches for #2 and #3 screws. Some of these items are available on Amazon. Otherwise I get them from McMaster Carr or MSC.
