Of course, it's probably not good to just sit there in the garage while your Cobra is idling and you just breathe the exhaust in. Hmmmm, maybe that's my problem....

I had all of the idle mixtyre screws set at 1-1/2 turns out. I re-checked them tonight and maxed out the rpm. Believe it or not I went in a 1/2 turn with three of the four screw to to get max rpm. Go figure, the smell is almost not there any more. I figured qnything less than 1 1/2 turns would be too lean. Still runs and idles great.

Sometimes you just need to go back to basics.
