What's this for?

[Rolf S. Ask]

that the cupholder thing is somewhat to make it easier to get to the airfilter to give the engine a small drink before starting it up after long time? As I have understood, the air filter is shaped as it is, so you just loosen the screw on it and then the petrol will seep down in to the carb...
Some old users of the CMP's in Norway told me this is the way to give it a starthelp. Don't take the filter of.
Or could it be some sort of wading equipment?
To let the air intake come up trough the dog house?
