Lately, it has been relegated to the back stall and hasn't really been run for several years.

The carbs had gummed up pretty good so I figured it was time to clean them up a bit...

I spread them out on the bench and found them to be in great condition other than being pretty dirty.

They're all cleaned up and reassembled with new main jets ready to go back in...

I just love old HS series SUs. They are elegant, simple little things...
