O.S. .91 Surpass Question
I just purchased my first 4-Stroke an O.S. .91 Surpass.I was wondering what the fitting under the engine(opposite the push rod tubes) is for? Would appreciate any help.

O.S. .91 Surpass Question
If you are talking about the nipple coming out of the backplate, it is a crankcase breather. Handy for applying your after run oil. Don't put too long a piece of tubing on it to vent it out of the engine area. Keep it under 6" if possible.

O.S. .91 Surpass Question
I have a OS .91 also. I use that vent for pressure for my smoke tank. Should I be doing that?
I bought this engine used and need to find a manual for it.
