Hey guys, I thought my carb was running kind of off so I took it apart. One of the metering rods was bent. The bent rod # was 49B. the other rod # was 47B. I would like to replace both rods and jets but do not know what size to put back. The carb # is 7041230. Is this carb supposed to have a retainer clip for the power piston? Can't figure how one rod got bent.
