After reading Gil's thread on his modifications to slow down the M-92 engine, I burned the midnight oil and disassembled the governor and cut two coils off of the spring, reassembled, and much to my joy and amazement, it now runs about as slow as possible without stalling.  I think I will leave well enough alone at this point.  The only other modification I made is one I mad to all of Jin's engines, and that is to put a small screw through the back of the wooden base that screws into the sliding bottom panel, to keep it from working its way out during operation.

I'm looking forward to seeing how everyone else makes out with their M-92, as they begin to arrive!

That governor sure has some tiny parts to deal with. Really put the new bifoculs to use!

Charlie. I run the same mix in all my engines. 1oz wd40 to 32oz coleman fuel. I oiled everything that moves with "white" oil, a light sewing machine type oil. Mixture screw is 1/4 turn open.
