Hi All!

Problem: Way too black sparkplugs, sooty and black.

Conditions: 45 idle jet, 160 main jet, 2.64 nozzle jet, needle in ordinary position, 1043 Q-Tech engine, 320/3 canshaft, 44 mm inlet valves, valve clearance 20/15, NGK 5 KOhm resistor caps, NGK BP6ET plugs, ignition timing set to 3-4 degrees static, HPN open airfilter, standard exhaust system

I've tried raising and lowering the needle withot result, same goes for nozzle jet having tried 2.64, 2.66 and 2.68 in various combinations with main jet and needle position. Choke system works, new gaskets.

Any ideas anyone??
