請問 師兄 對 Kyosho CRF 312T engine 意見

From some dyno inforamtion on internet, Orion engine only provide high power at high rpm zone but the bottom end power (low rpm) is very weak.

I suggest you may use longer (high torque model) tuned pipe. Using hot or Medium glow plugs would be fine.

Since this engine have been replaced by Picco-Orion CRF12 2008, I don't think it is easy to find spare parts.
