This was not a direct replacement the jets are undersized and the new carburetor made it run far worse so due to poor quality control I ended up waisting hours eleminating every possible cause multiple times to make sure nothing I had done was causing these new issues eventually causing me to disassemble the new unit and found when it was assembled at the factory the bowl had pinched and split the main O-ring in 2 different places when the bowl had been installed.
