I am looking for a carburettor for veteran Douglas motorcycle engine-13651. Could you please help me with this?

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.

2 3/4 rebuild well under way

I would like to thank members of the forum who helped out with some bits while the prewar spares is not operating so that I can get my 2 3/4 up and running in time for the Australian Douglas Rally next month. On the last dpuglas rally I destroyed a big end and did significant damage to the crankcases. I have managed to recover the original cases and have started puting it together.

One question - its ages since I have done a 2 3/4 - I am using new JP pistons I have had sitting in the shed for years. What ring gap should I use ?
