Please refer back to post #51 at the top of the page. The "Barrel" that the needle goes through is what causes my question. The one end as it's shown in post #51 is the end that is "counterbored", and the other end is just "blunt"....no recessed counterbore. Measuring with a dial caliper the raised ridge is within a couple thousanths of an inch of being centered end-for-end. The outer diameter of the ends (either side of the raised shoulder) is also within a couple thousanths of being the same diameter. The part will fit into the carb body either way, going in under the emulsion tube and main jet. Either way it barely extends into the main bore/throat of the carb body. I think the previous owner of the poor running '06 600 Katana I recently bought and have been working on might have had the carbs apart and I'm not sure which way the "barrel" should go in. I can't find any reference....anywhere, even in the service manual. Does the "counterbored" end go in first, facing the bore of the carb, or should the "blunt" end go in first? Since the tapered needle on the carb slide rides in the opening it seems it would be slightly richer with the counterbored end facing the carb's bore, and leaner with the "blunt" end going in first.
I'd rather get this right the first time so will say "Thank You!" in advance for clearing up the which end goes in first question.
