The saying goes “a picture paints a thousand words” , so a photo would help us help you. I would guess that it would be a “twin lever” carb , from their very fist models until the end of twostroke engined production , they seemed to favour and specify this style of carb. Ones for the earlier V111C engines seem more plentiful , as they were also fitted to numerous motor cycles , the ones fitted to the later 24/25c are like hens teeth.

A small number of Mk1s were fitted with the 80cc JAP twostroke.

Ian , I don’t think I can recall ever seeing a book on the 11C , the timing and points gap will be the same as the 24/25C.

Deffo an 11C, nice and original , still retains the proper carb and fuel pipe.

Andy.

[andyfrost]

Welcome , if it’s an 11C it will have a cast alloy cowling , pressed steel then it’s a 25C.

Chris , memory isn’t what it was , but I seem to recall that you simply undo the nut (left hand thread) and the sprocket pulls away by hand.

Mystery solved then , Alan , your collection of photos must be amazing !!!

I seem to recall they were a sort of maroon colour , (rather a similar shade to the small Clifford rotavators) and powered by the small 65cc BSA engine.

I’ve waited a few days to reply , I’m rather surprised that none have been forthcoming. The original question was regards to the Bux (Shay) 120cc twostroke engine. I feel it difficult to believe that it has in any way a connection with Villiers , it doesn’t share one common component found on any Villiers engine, likewise the actual design.

Geoff , you may well be correct regarding the sourcing of various parts from a number of different manufacturers. One BSA part need not make it a BSA engine.
I recall many years back doing the mechanical work on a Scammel fire pump engine for a chap , I fitted some new big end shells in it , a perfect fit straight out of the packet…….their listed fitment was for a Hillman Imp. Mr Childs may well throw some light on this mystery, there are few people , if any , that know more about British engines than him.

Geoff , there may be one minute clue there , the pic of what I’m assuming is a big end shell has the prefix 86 stamped into it.
86 was a prefix number used by BSA in alot of their part numbers , I may be miles of track , and it could even be a hepolite number.
I t would be well worth your while speaking to Paul Childs at Meetens , and quoting him that part number to see if it matches anything to do with BSA.

I’m leaning on the side that it could well be Albions own engine , you may well have a prototype that never actually got onto production.
Albion made a vast number of products , remember they even made pistols for the war effort , they seemed to be able to turn their hands to almost anything , so a stationary engine would not have been beyond them.

Andy.

[andyfrost]

Geoff , that may not be the original magneto , it could well have been fitted with a A series from new. it may be worth checking all the users of the A series mags ….just a thought.

Andy.

[andyfrost]

Have you checked the thread rates , that would give some sort of start. I would agree with Angus , it’s as far from a Villiers as I’ve ever seen.

Andy.

[andyfrost]

Brett , have they actually tested it , stripping and re-assembling is pointless if the coil or condenser is failing.
