The number stamped vertically on the side is the number you use. Any good parts man can get a kit from this number. Carquest & Napa have the best kits. They are pretty easy to rebuild. Keep the old gaskets to match up. The kit may come with more then one to cover more applications. Study the direction sheet to adjust the float level & metering rod. These are critical. Make sure the link from the throttle shaft to the metering rod shaft stays in the hole. These can work out & let the metering rod go to full rich. Sometimes you have to bend it in a little. Make surethe screws that hold the air cleaner bracket on are tight. These can fall out & destruck the engine. If you remove them use thread locker on them. Those are some pointers. If you have more questions post them.
