I am pretty desperate for a rear cylinder for my veteran Douglas 1917 2 3/4hp "W" model.   I there is anyone who may have one of these that can be re-sleeved or know where I may find one I would be very pleased for the help.  I have a number of engine parts that I can exchange such as matching crankcases, conrods, crankshaft, flywheel etc. Any help appreciated.

Does anyone have the specifications for the oil inlet valve spring for early 2 3/4 engines - Part number 424.   I have tried to order one from the club spares but apparently Jeff Swan is indisposed at the moment.

Hello,

I am looking for following clutch parts ( see photos ). The chain sprocket has a pitch of 5/8".
A complete flywheel is also welcome. Many thanks for checking your shed ; - )

Merry Christmas and a Happy New Year from Austria !

Hi Martin, I have a spare clutch/flywheel assembly, which I think is from a 350 model c.1930. I suspect you need something larger, but it is 8.5" (216mm) diameter and has a 22 tooth sprocket of 1/2" pitch. If it might be of interest, I'll clean it up and take some better pictures!
Regards,
Andrew

Hello Andrew,

the clutch internals are interesting for me. The flywheel backing plate has a diameter of 210mm.

Can you please send me photos by E-mail.

All the best

Martin
