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 everyone, I'm new here, so it's time to introduce myself. My name is Tomas, I'm from Poland. This year I became the owner of a 1926 EW. I'm in the process of restoring it and competing the missing parts. Can anyone help me find a drawing with dimensions of the part that holds the exhaust valve lift cable housing?
Many thanks.

Tomasz,

While I do not have one of these in hand to measure exactly, I have examined one.

The diameter of the collar is the same as the tube it sits upon. It is smooth on the outside (no knurl). It has a spigot that fits down into the inner diameter of the tube. It is a loose fit, no need for fine tolerances. The spigot is short, only about 1/8 inch long. The thickness of the collar is about 1/8 inch also. It is - of course - drilled coaxially for the Bowden cable. There is also a counter bore for the cable casing ferrule. Deep as practical but not critical as it can be compensated with the cable adjustment. The last feature is an axial slot to allow it to be slipped over the inner cable.
