[tenders]

The adjustment screw is very difficult to access when hanging down in a lazarette to tweak...and I'm saying this from a boat with a V-drive, which offers pretty good access to most of the engine.

Along the same lines as the water pump bolt extender, which is a stroke of genius, how about an extended version for the carb adjustment, perhaps with a gnurled thumbscrew at the end so the tweaking could be made without having to thread a long flathead screwdriver (or a hand) alongside a hot engine?
