Goat, I received both sets already, and they're nearly identical sets. One comes with an oddball size, other than that, they're the same jet. If you look at the picture I posted above in a previous post, you'll see that the additional 2mm is what hangs out of the carb. The dimension from the end of the threads to the end of the jet where it seats in the carb is identical, no issues whatsoever. The sets you have ordered will work for sure. I'm currently running a jet from the first set I received, although I'm still getting a small backfire on decel even after the proper mixture screw adjustment. I'll be pulling my carb back off for a 3rd time pretty soon to "up" my slow jet. Cheers bud.
