spark plug colour

Atomizer is av266

The AV266 is ok but not ideal for yours. Once you get the engine sorted, stick with the same size but but change to an AS266. Will have better mid range throtlle response.

Would you recommend to run the 9er iridium plug even in a standard P 2 engine (with BGM big box)?
