Things got a little more complex today. On checking the carb #’s I found that the 1& 3/4 spare carbs I have are model C4DF S which I believe may be original Tiger carbs. Does it make more sense to put the rebuild kit into one of the original carbs ? The only down side is that the C4DF carbs spent last winter uncovered outside although I don’t see any exceptional deterioration. Kind of thinking out loud here, probably going to try and fix one of the originals. Thanks for reading, if you have opinion one way or the other sound off. Bob
