If you need more power, get a bigger engine, or if it's not, put it on a tuned pipe.
2-stroke glow engines require back-pressure to run correctly.
Polishing ports will cause more fuel to collect into larger droplets, reducing efficiency.
You might in the long run get more top-end but at the sacrifice of mid-range performance.
Just my thoughts.
This one is about as big as they get in a 40 sized case. I don't
need the power. I just want to tinker and see if I can get more any way.
