Hello,
I have some carbs that have been left a long time and have this dark brown stuff, which is a hard varnish like gunge in them. What is the best way of getting rid of the stuff. Is is in the float chambers, on the floats, in jets, in the carb throats etc.
I was going to try ultrasonic cleaning in acetone, but acetone does not seem to shift the stuff.
Thanks

Ultrasonic is the best way. Don't know why acetone wouldn't work.

I now do the outsides and the float bowls, floats etc with walnut shells in my blasting cabinet...doesn't do shit for the passages...but cleans the outside of the carb great and often brings back that faint facotry rainbow anodizing.

How much does an ultrasonic cleaner large enough to fit a carb cost?

I don't own one. The local Yamaha/Kawasaki dealer has one, the parts mgr let me use it on a pair of CV carbs that had been stored for 4 years with gas still in them. I put the carbs back together, didn't have to replace anything at all, and the bike started and ran perfectly, and still does.
Made me a believer. I don't know what the solution was, probably just mild parts cleaner.

Hello again,

I strip the carbs into parts and clean individual parts- so you don't need a large cleaner. I think the sort that you see in Harbor Freight would be OK if the tank is about 4 or 5 inches square and same depth.

Engine case cleaning - straight in the dishwasher in the depth of night seems as good as anything - just don't get caught otherwise you loose your dangly things in a painful manner.

The Sylvan looks like the same one my local shop has. Seems like a good price and warranty. I'd get one if I could spare the cash.

You can get one of those tiny ultrasonic cleaners meant for jewlery for about $60-80- does wonders on all the jets etc. Works effing awesome! For the larger parts like carb bodies use a soda blaster. If you can't get your hands on one you can probably pay someone locally, look into autobody paint removal services. The soda is VERY abrasive, not what you'd find at home, it will take off any paint/coating/filth and the best part is it washes away leaving no residue. Can't beat that.

I love using this picture, the carb is SO DAMN CLEAN.
