Thanks I just hope he has some model A stuff as it would be better to swap for bits we need rather than cash that easily disappears on something else

Oddly, having conducted a Mk8C powered Excelsior for some while I found the forward facing carburettor to be no problem. You take one look and the first thought is that it will suck up every bit of road muck and water you come across but it was never an issue. I'm sure it must have swallowed some bits and bobs but it wasn't bothered by it.I did wonder about sucking stuff in but as you say its all about space
As to why it pointed forward, again, one look and you saw how much a rear facing manifold and carb would interfere with the hand gear change mechanism with both of them fighting for the same space on the bike. Remember, this engine was designed in the early 1920's when single speed belt drive bikes were still sold new and today's foot gear change was still years in the future. Designers were still finding answers to things we don't even recognise as a problem today. I think this is why I find vintage bikes interesting and modern bikes dull.
Cheers,
For 10 quid its an education, I paid twice that for a mower with oneof these engines!Cant buy much for £10!
Thanks I have found it, its a pity he has converted it to a different engine but I understand how hard it can be to get parts, it too expensive for usHave you any photos of it in position?
I think your gear has kick start on the left of the machine, and hand gear change, so maybe something like this 2 1/4 h.p. from 1923.

Thanks Leon I wish I could find more photos showing the actual bit

The Mk6C was a one year production only for motorcycles, 1923 if I remember rightly but continued in ATCO lawnmowers well in to the 1930’s. You can pretty well guarantee any Mk6C you find has come from an ATCO. They are not well suited to powering a motorcycle. Underpowered as their breathing is too restricted.The chap on the Villers parts stall told me this too, problem is if its got no brackets I don't think you can tell bike or mower engine apart?
Decompressors are common on all Villiers two strokes but sometimes are not fitted particularly on really cheap versions. You can see where it is meant to be but the requisite machining hasn’t been done.
I feel the same these days, though looking at stalls flogging cheap Taiwan tools and really over-priced "projects" doesn't help.Only one cheap tool dealer, some stuff was overpriced but we felt in general it was good
Average Joes clearing their sheds are great, part-time tat dealers aren't.
As it has flimsy mounts and a forward-facing carb I'd say mower, but I'm certainly no expert!The Bike and mower both had a forward facing carb
