This seems to be the problem I am having with finding a diagram for the carb as it is an '86 model cvh so I am guessing that the carb is probably an aftermarket unit or grafted on from a later engine. The carb has twin barrels and the idle adjust screw is a thumbwheel type which is parallel to the ground. There is a Weber tag attached to the carb but it has not aged well and is mostly unreadable. I would have expected the mixture screw to be in the area you point out but can see neither a screw nor anything resembling an appropriate orifice to contain one. If all else fails then I shall have to remove the carb, find the screw then refit it to set it up which seems a disproportionate amount of work for an engine that appears to be running well.

The idle speed screw is mounted at an angle - head downwards and has a coil spring acting as a locking device. the mixture screw may be concealed behind a blocking plug so from the exterior it may just appear as a blanked off tube moulded as part of the carb body. remove the plug to reveal the slotted screw head. The Haynes manual also notes that when adjusting the idle speed screw the electric fan should be kept running all the time.
