Hi Max
Thanks for the info. I will have to look into how to post images as it clearly didn't work. The upper housing is serial number 104949 so I am certain it is 2A; the donor part has serial number 303707 which I suspect is late model 3. I think the throttle control is correct except it has a metal lever, the carby is the later type, the fuel tap is correct and bolts that were in the box of bits are the same as the donor engine crankcase bolts. When I get posting images sorted I will add some images of what I have and some cylinders which look similar except for some differences with the fins around the exhaust port. I will have to find the right carby but probably have enough other bits to complete it. Aim is to get it running and think about paint later.
Regards
Greg
