i pulled this out of the tech articles:

Dry: Black Soot Buildup

Air/fuel mixture is too rich, the carburetor settings are incorrect, or the flame arrestor is dirty or has mounting problems.
Spark plug heat range is too cold for the operating conditions.
Ignition system problems causing a weak or intermittent spark.







thats what my plug looks like. i had the needle clip half way and dropped it 2 notches because it was lean now its this. it wont idle no matter how i turn the idle screw, WOT it bogs up and down, and midrange it hesitates when i give it gas. any ideas?

if someone can reccommend jets i have:
12:1 weisco .020 i run 118 oct
port and polish head
stock carb
stock valves and cam
k&n filter
stock pipe
