Hey Guys.
I just acquired a slightly used Webra 91 - 2 cycle.

No damage, a few nicks - but looks clean and turns freely.Compression feels real good.

No papers though.
Horizon Hobby doesn't list this motor anymore, and I don''t read German, so I'm left guessing.

I was wondering if some of you could suggest a prop size and if any of you can share some tech/specs.

I also noticed that the cylinder head has no drilled holes to accept a muffler.
The mounting flange for the muffler is flat, and the pitts style (?)muffler that came
with it is held on by a strap with a turn buckle arrangement, kind of like my old OS 40 rc from 20 odd years ago.

Not sure if this muffler will do the job..it's not much more than a box with a vent and two short pipes coming off the bottom.
(Hope to mount it on a Dragon Lady 60 next year).
