Hy GMCanada9430, welcome, could you tell us the year of your 9430 please. Do you realize that your truck is actually powered by a Chevrolet engine, as all the Canadian built GMC light trucks were. You have not listed your location in Canada either, could you tell us at least which region you live in please? Things like carburetor kits should still be available at your Friendly Local Auto Parts Store (FLAPS), hope that helps.
