Barr was one of the top villains in Florida in the mid-1980s, winning the NWA Florida Heavyweight Championship from Scott McGhee in October 1984. He lost the belt to Brian Blair before regaining it and eventually losing it for good to Hector Guerrero in late April 1985. Barr teamed with Rick Rude to hold the United States Tag Team Championship for three months before turning. He went to the World Wrestling Council in Puerto Rico having feuds with Super Medico 1 and Carlos Colon in figure 4 vs figure 4 leg lock match and later came back to Florida as a fan favorite, and in early 1986 he feuded over the Southern Heavyweight Championship with a young Lex Luger. After leaving Florida, Barr arrived in the WWF in April 1986 in a Lone Ranger-style mask as Jimmy Jack Funk, the storyline younger and unstable brother of Terry and Dory "Hoss" Funk, with whom he had previously worked in Florida. In addition to his mask, he also wore a noose around his neck to the ring. According to his storyline, he was a former amateur wrestler who missed out on the 1980 Summer Olympics due to the United States' boycott. With Jimmy Hart as his manager, Barr debuted to a decent push, but Terry Funk's exit from the WWF in early June caused Hoss and Jimmy Jack to fall down the card as a tag team under Hart. Their most notable match together was a loss to The Killer Bees in the opening match of The Big Event, a supercard at the Canadian National Exhibition Stadium in Toronto on August 28. As the only remaining "Funk" in the WWF, Barr quickly became an aimless "jobber to the stars", losing regularly to the likes of Tito Santana, Koko B. Ware, Hillbilly Jim and Blackjack Mulligan and teaming with a series of journeymen with whom he had no previous storyline connection. He remained in the WWF in this capacity until June 1987, but was released following a backstage incident with Haku. Despite rumors that one of his eyes had been gouged out during the fight, Haku himself definitively stated that the rumors were untrue and that he deliberately avoided injuring Barr. After the WWF, Barr wrestled in Continental Wrestling Association, feuding with Jerry Lawler. During one interview, Barr referred to Terry Funk as his "cousin". Then Barr joined World Class Championship Wrestling, where he was a villain at first but turned into a fan favorite in 1989 after parting ways with manager Skandor Akbar after he took offense to the derogatory things Akbar had said about Texas. Barr and Chris Adams were involved in a tag-team feud with King Parsons and Brickhouse Brown for several months with no clear resolution. After World Class, Barr returned to Portland, where he finished his career. While there, he won the NWA Pacific Northwest Tag Team Championship while teaming with Steve Doll on June 12, 1991. The title reign lasted eight days, as the team dropped the championship to The Harris Brothers on June 20. Barr retired in 1997, aside from a one-night return for NWA Carolinas in 2010. Barr now works in the construction business in Portland, Oregon. In July 2016, Barr was named part of a class action lawsuit filed against WWE which alleged that wrestlers incurred traumatic brain injuries during their tenure and that the company concealed the risks of injury. The suit was litigated by attorney Konstantine Kyros, who has been involved in a number of other lawsuits against WWE. US District JudgeVanessa Lynne Bryant dismissed the lawsuit in September 2018.
