Is this air cleaner dismantlable?

Not that I'm starting to fiddle with the Allen Scythe or anything, but...

The air cleaner is similar to this:

Can it be dismantled to clean, or is it into the ultrasonic bath and rinse as much pony and trap out as possible? I have a nasty feeling the two parts are pressed together, and would require damaging amounts of BFI to shift, but it really is solid with carp.

Also - there's a butterfly in the carb stub, between the carb and the cylinder. It's connected to the bottom of the engine somewhere (I'll be honest, didn't look very hard) by a linkage. Is this part of the governer arrangement? Seems a bit odd to control engine speed by effectively choking it to me, but I'm sure someone will educate me. It's a Villiers Mk 25 4-stroke.

I don't have one handy to

I don't have one handy to check, but I've always had good success by simply following the instructions!

Leave it in petrol overnight (or my favorite for eating scungy deposits, Xylene thinners), then blow it all out (from the inside, ideally). if the crud is particularly bad, a blast in the ultrasonic cleaner will help loosen thing up.

I've been known to do both at the same time (petrol+ultrasonic bath). Although that's a job for a nice wide-open space (with firefighing equipment handy) and will possibly win you a Darwin award, but it does work a treat on stubborn deposits!

If there's any paint left on the badge, you may wish to use a more gentle solvent though!

Xylene and Xylol used to

Xylene and Xylol used to arrive in tankers and had to be tested before being pumped into the tanks at a paint factory where I worked in the 1970's, I doubt either are very good for bare flesh, just a warning note.
