Hoping someone here can help. I have on older MTH 4-6-6-4 Clinchfield #670 PS1. There are small screws that attach the armature rods to the hanging machine. Not sure when mine fell out but I tried to run and noticed it’s gone. Attached are some pics of where the screw goes and the size, I got these pics from a good screw still attached. Any ideas of what size these are?
I tried to find a parts diagram but the engine doesn’t have a model number on the box.
Any help is greatly appreciated.
