I tried running this motor and had the same problem with a JP-3 pipe. I tried a JP-1 pipe which made it a little better, but, I eventually gave up on the motor because the lack of low end punch. I run on mostly 'tight' tracks so it was just the wrong motor.

You might want to also consider dripping a tooth on your clutch bell.

I'd try the 053 pipe. I used to run this motor with Ofna 053, NVR021 header and MC9.

Judging by what is being said I will say the motor is over shimmed for the nitro % being used.... I am not sure of the clearances or compression on the P3 21.... But by the description of the performance it sounds like it needs a bump in compression....

Yup what Maximo said, Just 'cause its acting rich on the bottom end doesnt mean it is, Up the comp. it pings drop the comp it boggs down make sure your running the right plug too...... Only 'cause I just went through this with my engine.
