No, it will overflow running at a stop light and it will overflow when the engine is off and the tap is also off. It's bugging the deal out of me. Sometimes it's like it is being starved, other times the fuel smell is strong.
This is often caused by a dimple on the float tang:I've used the fingernail file in my Swiss Army Knife once to fix it in the road. 
It does have the dimple. I spent several hours ar Lloyd's (TwoTired) tonight. The dimple is so deep we couldn't get rid of it even with a fine grinding wheel and variable speed rotary tool. We were able to make it shallower and Lloyd reset the float for me. We also replaced the O-ring for the needle seat. The #1 plug was very spooty so we cleaned and gapped it. I pulled the other 3 and they looked fine, I gapped them and reinstalled.
Lloyd kindly provided me a full points setup as a loaner until I get home, but for now I am going to continue to run the EI with the cover off and hold the points as a backup.
I also pursueded him to part, for an eminently fair price, with a stock F seat to replace the smaller aftermarket I installed last week.
I also saw his amazing RC airplane collection and wood shop and his vintage 30's Chevy coupe hotrod he bought way back in 1969.
All in all it was a great day and a real treat to meet Lloyd and his wife.
They offered to put me up for the night, but I wanted to put some more miles on to shorten tomorrow's ride to Alpine and the Coronado Trail Scenic Byway.
