The low speed needle seal being referred to is #20 in the following parts breakdown:

This piece surely does seal the air out of the low speed mixing pocket from sneaking by the threads on the needle. The price is ridiculous and I’m not even sure it comes with the carb kit. But, like Optsy says, it is trick to remove without damaging the carb, so be careful. Again, I just thought it would be easier to try another "known good" carb first to answer some questions. We can rip into your carb more if your engine idles OK using the know good carb….
