electrical and ignition Spark Plug Color, Please Look

[zinz]

Can y'all take a quick look at this plug and tell me if I'm too rich, too lean, or just about right?

Set up:

NGK BP6ES plugs gapped to 0.033 with a couple 100 miles on them

Weber 32/36

Stock compression pistons

292 cam

IE dizzy with Petronix

Header

Timing unknown

Plugs cleaned/regapped during recent valve adjustment

The Weber is off the car and dual Solexes will get fired up tomorrow. I've installed new plugs with same gap

I've always thought this Weber ran rich, but black spot is only seen on the outer rim and the electrode looks good.

All four plugs looked the same.

Thanks for the input

...forgot to add... Red Coil

One curious thing was that after the valve adjustment it it didn't idle very smoothly. I rechecked the plug gaps, all the wires were snapped on. I made a small idle screw adjustment which helped, but didn't solve it.

Never checked the timing... I suspect my issue lies there.

Any recommendations on a timing setting for the new Solex 40 DDHTs ? I bought a Ti dizzy with proper advance curve for duals, but will start things off with my old IE dizzy to keep the variables to a minimum.

This is my first attempt at dual carbs and have read a LOT, so hopefully things will go smoothly.

Looks purty but you need to drive the car harder

If I can ever finish this blasted dual carb conversion, I'll do just that, Ray!!!

If anything, that's a little lean.  But I'd say it's darned close to spot- on.

But it'd run better if he painted 'em red!
