We have investigated proximity-induced supercurrents in single-walled carbon nanotubes in the Kondo regime and compared them with supercurrents obtained on the same tube with Fabry-Perot resonances. Our data display a wide distribution of Kondo temperatures T(K)=1-14 K, and the measured critical current I(CM) vs T(K) displays two distinct branches; these branches, distinguished by zero-field splitting of the normal-state Kondo conductance peak, differ by an order of magnitude at large values of T(K). Evidence for renormalization of Andreev levels in Kondo regime is also found.
