I recieved this muffler with an old OS .90FS, and am wondering if anyone know what it is for. It has the same threads as the .90. I sold the .90FS, and this is still laying on the bench. Was this the OS 1.20FS muffler?

VT 49

It looks pretty big for a .49.

You ask what it is off of and I told you. If you don't like the size take a hammer and smash it flat.

I think I will do that.

The HP VT.49 was in the same sized crankcase as the HP VT.61. Back when this series of engines was designed, Europe was going through a quiet craze too.
