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.

Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

Can anyone help identify this gearbox found in an old barn which has been suggested came from a Douglas. It has  the marking PATENT H  5007 it's appears to be 2-speed with ratios of 1:1 or 1:0.6  the output shaft on the opposite side being lefthand thread and a  number 163 stamped on both castings. Hope the photo helps.

Most definitely a Douglas gearbox, but it is a 3 speed. It is from a 3 1/2hp or early 4hp machine with the cone clutch on the final drive side of the box. I'm sure there will be plenty of people interested in acquiring it!
Cheers, Graeme

Hello All, From where I looked on ebay the said 4 hp box has expired with out a bid. Like I say A $ 400 would have been the price I would have paid had the location been in Aust or NZ. I am in no hurry one will come one day or an alternate transplant will take place. regards Alan
