if your not comfortable with the carb rebuild, any lawn mower shop can do it. pull the carb off and take it to them. you will need to provide them with the engine model # and code (usually on a stamped metal plate somewhere on the engine tin) while your there get a new O-Ring for the oil fill plug. it could affect crank case pressure and therefore fuel pump operation. on the seafoam. it's great stuff. i run it in the fuel on all my small equipment. keeps the fuel dry and keeps from getting varnish in the carb.
