Hey guys, I was wondering which plug to get for my blaster. Its bore over .090 making it heat up abit fast I guess? and i pull my first plug out after rebuild (2 tanks running 30:1ish) because i have to keep kicking 10+ times for cold start up then it eventually bogs down till it cuts out and my plug is black so it means its filed.? Should i run a 8 or a 9 plug? or is it a special plug I need to pick up since its such a huge bore.
