This little factoid tells me that mix is almost certainly too rich.
Because the A4 uses an updraft carb, a properly adjusted mix should be a little hard to start when cold, even with full choke.
Some time back, I followed Hanley's example and installed an Air:Fuel ratio gauge on my A4. That, and an adjustable main jet, lets me get it spot-on at the proper 14.7:1 ratio. And it normally takes about 3 trys to start with full choke when cold.
A too-rich mix will run cooler, and produce more plug fouling.
EDIT: Once again, Dave types way faster than I do!
