Re: what to do with broken plastic "gasket" O-ring on carb that fits to "intake manif
Actually, gasoline resistant sealer is better than any 'O' ring because it doesn't rely on pressure and tightness to retain a good seal. Throw the 'O' ring thingy in the trash and pick up a tube of Seal All from an auto parts store. Or, any gasket sealer that will stand up to gasoline. Most silicone based sealers do not...read their labels.
