I have Efco 156 needs a piston, was wondering if anything else crossed over.
It is a window piston and looks very similar to a Stihl 028 piston. Both 46mm
Specs of Efco are
46 mm Diamiter
38 mm top of piston to bottom of skirt
12 mm wrist pin x 32 mm wide
15.5 mm top of pin to top of piston
You can see ring stop pins in pictures. Also rings are 46 mm x 1.5 mm wide.
By the way got this as a parts saw would like to make it a runner looks like a very low hour saw.
I think I can save the cylinder top beat up some, side walls look ok.
