that was probably me with the carb o-ring info. I have caps on both of mine and the o-rings are the same size. I don't recall off the top of my head what size I got but they did work, however they were not the exact correct size. I may try to go back and get the right sized ones next go around. I'm going to be tearing into it again in the next week and will update what I find with regards to sizing and parts. I ordered a Kawasaki float bowl gasket and will see if its the correct size for the 950 carbs.
