Re: Soak a Carb in what?
depends on the laquer thinner -- some are nothing more than acetate and alcohol, others include stronger solvents.
I like B-12, it includes acetone, methyl ethyl ketone, toluene, alcohol and some other stuff thrown in besides.
Only soak the metal parts. If you have plastic float bowls, soak them in seafoam -- it'll take longer but it won't melt 'em.
