Lister D carb rebuild for Barn Find Lister Stationary engine and aerograph compressor

I purchased this Lister D petrol (gasoline) engine that came on a trolley with an Aerograph air compressor.
This video is about the steps taken to produce a carburettor that is primed, ready to paint and install back into the engine.
They were used in the village forge in Cullworth (Northaptonshire).
I would be interested to hear from people who either have seen this running or know of similar setups in forges.
I would also welcome information on some of the things shown in the video such as the handles on the trolley.
Please get in contact if you know anything about aerograph compressors especially if you have technical drawings.

No air valve spring?

Probably camera angle and lighting not optimal so it is difficult to see, but it is there!

I thought that but it goes off camera when putting spring on valve

[@carburist]

Yeah sorry! At this time it was all being recorded on my phone as it was the only recording equipment I had. Did work out well tho!

Air mixture man.. I'm new to Lister d's... This air valve.. obviously that valve checks flow etc but does it help restrict air and richen mixture?
