Just needs 2 simple items needle seat for the float bowl needle and the sealing washer under the float bowl nut. This had a dirty carb and it would start on the first turn of the motor with a few drops of fuel. I had cleaned the whole carburetor and fount the seat was dry and swollen and somehow the washer for the bottom of the bowl was missing. All parts inside and out are moving on the carburetor. I was surprised no pitting whatsoever on this old carburetor. The 1969 trac team snow blower this came off of was always under cover as you can see the shape of the engine.
