Safe way to soak aluminum carbs

I have a set of aluminum carbs I need to clean and rebuild. Whats a save way to do this without damaging them?

 

Berryman is about the only solvent that works on today's gas/varnish.

 

I use gunk hydroseal II, just don't get it on plastic or paint.

 

sock juice! Works everytime

 

I've always used laquer thinner myself. The varnish just comes off in a powder when you are done soaking and the carb has dried.

 

Don't use Berrymans. Try cooking your carbs:

It will get the varnish and gunk out, guaranteed.
