This from Sir Atwell Haines, the legendary one...
Take a pencil, cut off the eraser end, so as to have no metal that will mar
your precious housing.
Remove the Damper Assembly.
Remove the diaphram (watch the alignment tabs etc for re-assembly).
Remove the needle from the piston.
Take pencil and put it in the hole that the needle assembly came out of.
Push up. The whole thing will pop out of the bore...washer and all. Do
this over a clean rag/newspaper so as to catch all the stuff. Washer is
very hard to find new, so make sure you don't lose it!.
Here is his original to me that I followed...works like a charm.

Good luck, it's not too hard.

Do you replace the O-ring in the dash pot during the rebuild. It sounds
like oil is leaking from the dash pot into the carb and being burned off.
To replace the O-ring you will have to fish the star washer that is
holding
it down out with a thin stiff piece of wire with a "J" at the end.
It is not hard just takes a while to fish the washer out.
