when i say that, my M3T i have run in using same fuel same amount of fuel, and completely different engine as far as pinch is concerned. the M3T needs more run in.
All the reds engines are modded and hand matched from The factory, I have personally lapped 11 m3t piston and liners and found all of them pretty much equally matched. I assume the 21s get the same attention before they leave Reds factory. Id be getting a spare piston liner set if you are concerned as they are cheap. Hope you are not going to the nats with one engine for your 1/8 scale LOL.
