Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I have a  Craftsman single stage snow blower which has been sitting for three years now unused with gas in tank. As you can imagine there is plenty of varnish in carb. So I did dismount the gas tank and cleaned it out  along with the fuel line . Thats the easy part. My question is what do I soak my carb in to losen up the varnish and crud build up ? By the way I ordered a carb kit which includes needle valve,VITON seat and bowl gasket.
