    Plug read help please?

    I removed the plugs from the engine today before getting into this valve adjustment and wanted to ask for some help reading them.

    From left (#1) to right (#4), what do you all think (too lean, too rich, just right?):

    Doesn't really tell you much honestly. To do proper plug reads you have to do chops in the individual circuits. That's just giving you an overall read or the circuit you last spent a fair amount of time in. Or on choke. Choke will usually make them read a little darker than actual running conditions. But, overall they don't look out of whack one way or another. I guess maybe three is a touch dark but I wouldn't suggest messing with anything unless you do individual position chops.
