    Product received as ordered. Perfect fit for my power generator. Thanks

    Perfect fit replacement part
    So glad this part was available as many for older tools are not. This part seemed a bit stronger that the one that was being replaced, as the metal around where it mounts to the carb looks and feels thicker. Good thing because the old one cracked through the mounting holes due to vibration over the years. The reason for 4 stars rather than 5 is there was no gasket as depicted.
