Ok at last some progress to report. Timing backed off to around 31 degrees.  Bike fired and ran for a few seconds, as it stopped the kickstart gave a big rattle and clattered up into the awkwardly positioned high level pipe (runs outside the frame under the oil tank). This happened again the next time I kicked it. After a short break (whilst I tried to move the exhaust up slightly to reduce the kickstart problem) I re fueled the carb from my temporary bottle and pipe supply and tried again. This time nothing until a loud backfire through the pipe (no kickback).  After this I spent a few minutes kicking but nothing from the bike. A good spark, and plug ok. I'll try again at the weekend.

You can rotate the stator plate for fine tuning if not enough movement Iíll take the rotor off and move it slightly.

Thanks once again for taking the time to reply :).
I've checked the rotor again and timing as per the instructions from electrexworld looks to be spot on. I located TDC using a degree disc measuring either side of TDC and then finding the centre point. Stator fitted as their diagram.
I haven't tried to start it again as nothing has changed. I've fitted a temporary air filter so (waiting for side cover to arrive before I can fit vokes one).
I previously fitted an electrex on a Bantam that i had with no issues, its a real head scratcher this time.

Ok so head repaired, camshaft outer bush changed and reamed and all back together.
I fed some petrol into the carb and tried to kick some life into the bike, nothing at all. I tried to choke the carb a bit (rag over the intake) which produced an engine ignition but also a massive kickback through the crank (ouch). Checked the timing (with a disc) which was spot on as per electrexworld 35.5 degrees. I retarded it very marginally. After the kickback I removed the footrests which get in the way with the U shaped lever and tried again. Same result, nothing until I choked it then bang a kickback (which I was more prepared for this time but still not good).
Any ideas what next? The fuel is from last summer which maybe doesnt help but how would that explain the kick back? I've checked the timing again and it looks spot on.

PS I seem to have created a second log on in the past with a different name on my work computer. TDub62 is me (Guy).

I've just bought a new camshaft bush for my distributor 1959 engine which came as a non runner loosely assembled project. The bush I received is a straight tube, the one on the bike has a lip on it with a peg. Is it possible someone has put the wrong bush in previously?

I have better pics but struggle to upload them onto the forum. It looks like it may have been repaired previously as the pushrod tube opening has a slightly flattened surface near the damaged bit. The damage is like an impression of something but probably too deep for that. Sadly it came to me like that. Think I may take it to park engineering at Malton near where I am to see if they can repair it.

Oil pump checked and all seems ok in theory , i blew down the NRV hole but no idea if it did any good or not. Anyway all back together and and it turned over ok as previous. Checked valve clearances and the I put the plug in and turned it over gently to check compression. A hissing sound could be heard on compression which after much squirting and soaping around the head gasket joint I thought must be coming from behind the push rod tube. off with the head and sure enough a small fault and repair between the tube and the chamber with a small rectangular impression in the face. I;m going to see if i can get a better repair done and guess I will need it skimming as well. The bike has had a new high compression piston fitted and I'm slightly worried about adding a skim to this. I've read that you can get slightly thicker gaskets possibly from BSA singles in the USA. Anybody know of a UK supplier.

Thanks again, I haven't had chance to get out after work tonight but will hopefully have a look tomorrow and let you know how things progress

Hello thanks for the help again. i stripped the oil pump which looks ok. i think the NRV bearing may have been stuck. Its free now. Can you tell me which hole leads to the inner NRV?

Sorry but another question. Before stripping the bike I checked to see if oil was going back into the tank. The pipe that i thought would let oil back into the tank appears to be a sealed tube that sweeps upwards and ends up inside the filler cap opening. I checked inside with a mirror but couldn't fathom out how the oil would return. No doubt I'm missing something obvious!

Ive just put 500ml oil back in the tank and will see how much has drained from the sump in the morning. Not buzzing about splitting the engine but not convinced by the valves on the infeed pipe as there seem to be conflicting stories on their success rates.
Thanks for the info.

Ouch not good news, is there any sort of test before i set off stripping it down. I haven't split one of these before is there a good manual anywhere?

Does that mean splitting the cases to check it out?

Thanks for that I'll get back on it when I've warmed up a bit!
