It’s necessary to maintain a snow blower, as a dirty carburetor can keep a gas-powered snow blower from starting or cause it to emit dirty, smoky exhaust. A carburetor cleaner will dissolve the gunk and debris so your machine will run more smoothly. To clean the carburetor, you’ll need to remove its cover, a process which may be different depending on the make and model. Consult your owner’s manual to find out how to reach the carburetor.
