The Enya 30 has the same bolt spacing, so why not give your OS the same treatment?
I'm away from home, so don't have my figures in front of me. I remember liking the engine a lot, but from figures I've seen it is not nearly as powerful as the FX.

I used a TT .46 Pro muffler on the Enya .30 as well as a .46 Jettstream muffler.. I haven't tried the big muffler on the OS yet - I the TT .25 muffler fit without modification for a test run to see if the engine was gonna even run. Next test will be a .35 Jettstream muffler (stock bolt spacing for OS/ST .21-.32) and later the .46 size mufflers. I didn't get the stock muffler with the ..25FSR, so I used what was handy and fit. Part of the reason the FSR isn't as strong is likely due to the timing. The FX is timed hotter and likely has a bigger carb. Fear not, I will test different carbs and exhausts to see what my FSR can do - I need some data to compare for when I put the Davis head on it. I've been so busy, I haven't had a chance to run the FSR further.
