So, I have got the bike ticking over (it last ran in 1972, so great to have her back). When I de-clutch, the engine dies, so the bike doesn't move. Would this be a timing problem or carb? I am running a Boyer electronic ignition (including coil). Grateful for ideas. It might be worth mentioning that I had to wind the ignition back to between 80 and 90 degrees advance before it would fire.

Dies?
Hello Mike, when you say 'the engine dies' do you mean it 'locks-up' or just stops (as if you have turned-off the ignition). If it locks-up this would imply that the clutch is not free (as Robert suggests) and you have a gear engaged. Having to set the ignition timing back so far certainly indicates something else but I'm surprised the motor runs at-all in this state. The light Twins depend on very accurate timing to run correctly.
Keep us posted on this - I'm intrigued ... .

Yes, I'm new to this! I…
Yes, I'm new to this! I start the bike in neutral, when I engage first gear and apply revs the engine doesn't run as smoothly as when it is idling. Then when I release the clutch the engine stops as though I had turned off the ignition. I have been rebuilding the bike myself, and while I would love to get it going myself, I am prepared to pay to have an expert finish the job.
when I set up the timing, I followed the procedure in the owners manual (and explained in many threads on this forum) but nothing happened at the correct angle of advance. I put that problem to this forum and received advice on the one hand that is should run if set up property and on the other hand to keep advancing until it fires. In this case, the latter worked.
I hope that helps

Mike,
You first reported your problems starting the Jubilee in 2022. Two years on and you deserve to be running. Summer days are getting shorter.
Are you in UK?
What county are you in? Let us know and perhaps the offers of help will flood in.
Can't be that much wrong with it if it fires up and idles.

sounds like you are new to old Nortons ?, clutch may be stuck, Cant follow what you are saying about the timing. Timing is pretty critical on these short stroke motors .Would pay you to get help?.
