Pond 510 Running Rich

Thanks for all the comments guys,  I truly appreciate the help.

Finally figured out how to reduce the size of the pictures from my digital camera.  Here is a pic of the #4 plug.  The #1 plug looked the same.

Let me know what you guys think.

I am sure you have done this, but ignition timing must be set before any tweaking on the carburetor. Just trying to cover the basics first.

What are you running for an ignition?  Doesn't even look like its trying to burn that plug clean

Yep, set at 40 degrees at 3-3.5k rpm.  I may back it down to 38 as it's straining the starter a bit.

MSD 6AL with MSD distributor.  The vacuum advance is plugged.  Everything is new.  It might be a faction of total run time as it's spent more time idling that any thing else.

I realized we are talking about mixture here but I went back and tried to see what plug you're running. I didn't find if you said.
My 441 has to do lots of idling in traffic so I use a hotter plug (45s) and they stay very clean.

I'm running NGK R BKR6E plugs.  The car is a weekend warrior and rarely gets driven but if it does, it's on the street only, not in traffic. Looks to be in the middle of the heat range, nothing special.
