RE: New Evolution 10cc gas engine
I would like to see how it responds with the mac's black muffler, one piece unit. We are talking the extra volume version for the 55AX and 60NX. My 55AX's really come alive with this extra volume version muffler since it is larger than the .46 version.
If a certain pipe is tuned for glow, I don't know if that tuning is necessarily optimal for the same engine in gas.
