Ran it out to 5500 and shut it off to pull plugs. 1,2,3 and 4 look like this. Plugs 6 and 8 look dark brown I can't pull 5 and 7 because the header tube runs too close to use a ratchet, and naturally the tube is hot. Have 82/92 jets in, should I go up one size in the primary and down in the secondary? How's the timing look?
