Yeah, I lost custody for 12yrs after a divorce. Here's a pic. before I lost her. I was running a 3.5 Briggs from a pressure washer. So when I got her back I felt she deserved better... But I don't know alot about Dellorto's and don't want to screw it up right off the bat... I know they ar using ub20s on hs50's but what does the bs stand for:shrug: and will it work:confused:
Its been my new happy hour this winter. lol
