Hi everyone..
I was just wondering what the original shimming size is on a stock OS12TZ-3port? I'm planning to run 30% nitro and want to know how safe it will be on the life of my engine and its performance.
I'm currently on sea level with relatively low-med tempretures (between 10'c-15'c). I burnt three OS P7 pluga and a P6 within 3 hours of operation. The P6 only lasted a tank of fuel untill it was cooked.
I will be running on an open track with high speed cornering and few tight bends.
Thanks..
