Hi All.

Iīve been able (My friend Quique did it) to modify an OS 35s in order to attach a standard muffler screwed in typical manner. The old (1995) plain bearing Stalker 35, 40, 42 and 46 silencers are a perfect fit.
I am planning to use a tongue in a future, there is other OS engine with the same space between screws?

Thanks very much from Spain.

you just drill  thru the  holes  in the  inside  edges of the  exhaust  and out the back side of the  case, you can then use  tube or tongue mufflers  putting them on from the back of the motor
It is 1.25 span  and is  the same  as the  NEW OS LA 25   and the  ST 34 
some other engines  take the same size
some OS 35 S  have the  holes inside the exhaust drilled and tapped, other have  just a block of metal there that you can drill, same for the  OS 30 S

By the way, we have checked that tighting excessively the silencer distorts slightly the case, as with the strap.
