carburator "varnish"

[redzap]

You know the build-up of copper color that builds up on the bottom of carbs?  Does anyone have a suggestion on the best product to remove it?

[balibeemer]

The brown deposit is residual wax from the fuel. You can remove it with carb cleaner,or,ifyou are environmentally conscious, pure "simle green" and a toothbrush.

Several carb cleaning products will work on this fine.  A product that I have yet to try but which a number of people recommend to me is
called "Sea Foam", which is used to clean fuel systems in marine engines.

Berrymans B-12 will dissolve it immediately, but be careful to quickly flush it off plastic parts and don't let it sit too long on nice shiny paint.  I find it to be one of the most powerful solvents available "over the counter" and would be lost without it.

Berrymans B-12 is the stuff, unless you're in California. I've been led to understand that it's banned there!
