Hi Anthony, welcome to MOT!!
Very nice looking early Mini, I look forward to meeting you and hearing the story on how it came into your life.
Lloyd at BAS was using an 848 powered car as his daily commuter, so he'll know what to do. I've heard good things about Kip also, but I haven't had them do any work on my cars.
The SU is a fairly simple carb, but it took me a while to wrap my head around the jet size changing as the needle moves up and down. If the bolt pattern to the intake manifold is two studs/nuts vertically, it's an HS2, common on the 850s originally. If the bolt pattern is diagonal, most likely an HS4.
The one thing I've heard constantly over the years is... if you think it has a carb problem, check and fix the ignition. It's not for nothing that Joseph Lucas is half jokingly called "the prince of darkness". If that doesn't solve the problem, then it's time to go after the carb. Then again, the new gasoline formulations don't store well, and aren't always kind to the rubber and plastics in the fuel systems of the Mini.
The Dallas All British Car Day is going to be on Sunday May 1st, 2022 at Dreyfus Club Pt on White Rock Lake.
www.allbritishcarday.com I plan to be there, although I'm not sure I'll be able to bring a car this year, as the sports teams say, it's a rebuilding year for me. I will be wearing my pride via Mini themed t-shirt though.
Cheers,
Jim, Diana and James Gambony
