Monty I bought a P5XLT last June or so, and i went on Novarossi web site and there is new exploded view of the engine as of 5-16-2011. All of the part #'s are the same even the breakdown of the carb. But the carb as a whole is a new number. It went from 24069 (old) to 24063 (new). I thought I had the new carb already, whats the difference
