BSA C11g Running problem

[RayC11g]

Hi, i am at my wits end! Can some one please give me a pointer.
Bike has been running well. Pulled out of garage, started and ran ok. The next day
started up straight away but as soon as I turned key over to other position bike
struggles to run and conks out!
I have replaced these parts now
1) new ignition switch.
2) new coil.
3) new plug cap, ht lead & plug.
4) new rectifier.
5) new wiring.
6) new battery.

Have even tried used condenser(one which i've Changed when I fitted new points)
All this and bike will still not run, starts up at first kick but only in start up mode.
Can anybody help?
Thank you.

Hi, just realised what i've done!
It's been stood up over winter, done some unnecessary work when all I had to do was look which way the key was turned! Key turned wrong way! Cheers.

At least it was an easy one - eventually!
