Hey folks

I got a 49-pi (not the second version) and noticed that the muffler does not have a pressure outlet and where does the other vent on the crankcase be postioned at? Any suggestions to help me with this first time rotary engine would be appreciated greatly.

These are not very common engines so if you don't get the answers you are looking for here, try posting these questions in the OS engines support forum.

You can install a tap into the muffler for tank pressure, and the vent goes down. OS makes a special plug for this engine and you will not get good results without it.

I believe that OS discontinued the special plug for the Wankel. I think that the 4 stroke plug is the replacement. And as I recall, that engine does not need a pressure tap. I have seen several more posts on this engine. Don't take my word for gospel though, I have a Wankel, but have not built anything for it yet.

Good Luck, Will
