Just getting started on my latest project (2000 VT1100T), and I'm already running into issues. One of the air screws had gotten stuck in the right carb, and the PO had tried to drill it out. He ruined the carb body, so I bought a used pair off ebay. I'm disassembling the new ones, and both air screws are stuck. I've soaked them in WD-40 overnight, but they still wont budge. I'm thinking about applying a little heat, but that seems drastic. Is there anything else I should try first? Thanks.
