What's the difference between a 029 and a 029 Super?

My friend is going to do some work for me so I'm giving him my 029 (bought new in 2000). We took it out today and I noticed it says 029 SUPER on the air filter cover and of course Farm Boss on the bar. Is there any difference between the 029 and the 029 Super? Not that it matters I just never noticed it before. Thanks NYH1!

The 029 is 45mm bore, the 029S and MS290 is 46.

Is there any difference in performance?

Yep.. the 46 is slightly more powerful.. Maybe 0.1 or 0.2 hp, I forget..
