Two pieces of wet and dry paper with a hole cut out of the center, could be used back to back above the moving part of the lever to add a bit more friction, until you can get the proper washers replaced
Also a bit of thread lock on the screw
Worth a try Dai

Edit. Or just buy a new choke lever

In my experience, those levers do have this tendency to loosen. I have one on a Bullet and another on a Commando. If the central screw is tight enough to prevent the choke from closing itself, the additional friction makes it difficult to operate.
Also, setting the central screw to what feels 'right' and then operating the lever back and forth a few times always results in the central screw coming loose.

I've taken both apart and in each case the wavy washer was almost flat when removed. I duly replaced them with new ones, but the problem still persists. It seems that the friction between the central screw and the top cap is the root of the problem.

I suspect that one solution would be, as suggested, to loctite the central screw in the 'right' position, but I have not gone down that route for fear of damage to the monkey-metal casting if I need to remove the screw at some point.

So, it has just become another use for the screwdriver I keep in my jacket pocket.....

(Strangely, the problem is no worse on the Commando, even though the lever has to operate two chokes with a return spring in each.)

One thing I have considered is to find a way of fitting a dowty washer so it's pushed against the moveable part of the mechanism when the bolt is tightened. I reckon the slight friction of the rubber seal would be pretty effective in this case. I've seen them used for a similar purpose in another application (nothing to do with motorbikes).
