I am the guy with the sluggish 1974 sb with the carb problem.I was discussing my problem with my boss,who has quite abit of experience with bugs.I was telling him that I have been on the air speed forum asking questions and he told me to say " hi" to geoff.His name is Aaron Smith, he said that geoff got him guys calling him to do welding repairs on cars about 8 or 10 yrs. ago.
Anyways , just thought I'd pass that on to you (geoff)
