carb gummed up

I was just given a 20 year old sears craftman snowblower that is about 20 years old and hasn't been ran for 19 years. It will turn over very well with starting fluid. But is is not getting is own gas. What is the best way to clean the carb?

Hello Insman...

Go to an automotive parts store and buy a gallon can of carburetor dip ( 8 to 10 bucks). Remove the carburetor and disassemble it. If it's really gummed up, you may have to soak it 10 minutes before you can disassemble it. Take out the jets, mixture screws, everything you can except the throttle and choke butterflies. Follow directions on the can. When you remove the carb, blow it out with compressed air...wear safety glasses because some cleaner may blow in your face. Make sure all passages are clean... a torch tip cleaner works well, or a thin piece of wire will do.
Replace needle and seat, check float and replace if needed, replace bowl gasket and any other gaskets, and reassemble. Make sure the float is level. To do this, turn carb upside down with float installed, look at float. Make sure it is parallel to the carb body. Adjust if necessary. Install and adjust.

Carb cleaner is an irritant, wear chemical resistant gloves and safety glasses! Follow warning labels on the can. Good luck, and keep us up on your progress. If further instruction is needed, post your engine make and model so we can be more specific with our answers. THX!
