: I would like to hear anyones ideas on the best way to clean gum and varnish off of an old carb.
: This one has sat for about 30 years and is coated inside and out. I would like to hear anyone else's methods for getting them clean.
: I would like to soak it in something to get the inside really clean.
: Thanks to all who respond.
Von -
Presuming the old carb has no plastic parts, I've found Strip-Eze (or other methylene chloride-based paint stripper) works better than anything. Simply paint the stuff all over the disassembled carb parts. Wait a half hour or so for it to soften the varnish, then wash everything off in kerosene or hot, soapy water.
Just make sure there's no plastic floats, rubber diaphragms, etc. in the carb - they'll melt IMMEDIATELY on contact with methylene chloride.
