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.

Gents,

Just received new head gaskets from the Club, on fitting should I apply a light grease coat or fit dry?

Yours in hope/

Fit them dry - then check the head nuts regularly until the gaskets stop bedding down. The modern non-asbestos gaskets seem to squeeze down more than the original gaskets - often resulting in premature gasket failure. Applying a coat of Coppaslip to the stud threads also helps.
