A bike we sold at the scooter store I turned wrenches at. The particular one I had a chance to ride, was kitted with a variator upgrade, bored and porting, and a tuned exhaust. Was a head snapper from standstill. I don't think your fix will be an immediate problem, but safe to have the gasket bits, just in case. And you know how to work on carburetors, so it's an easy fix. One thing, if you find yourself disassembling Japanese carburetors with regularity, is to get a JIS, ( Japanese Industrial Standards..) set of screwdrivers, at least the #2 and #3's, as you've probably found that normal Phillips screwdrivers don't seem to work great on float bowl capscrews.
