I could do with some help understanding the route for cables for front brake, choke and throttle- if someone could post a photo that would be great. 

a further question, mine seems reluctant to Start or run without the choke full on. How soon after starting should the choke be off? my mind is telling me the solution lies with the fuel and air mixture, so could it be that the problem is due to no paper elements in the pancake air filter?

 

as always, any help greatly appreciated

Not sure how the classic routing should be but this works for me. (Sorry it’s not a better picture) Originally I had the throttle and choke cables routed over the tank mounting bolt and under the tank tied alongside the wiring harness. This caused the revs to rise when I turned the bars to the right. Therefore I routed the throttle cable to be free on the outside of the tank. With regard to you needing constant choke, I will assume you have sussed that the choke lever position should be pointing towards you for normal running. Next, if you have a bush type pilot jet in the carb, I would start there.

Thanks for the photo 

I too suffered from the over revving problem, but I’m worried that using the route you have the throttle cable could catch in the steering lock “ears”. 
I was aware of the choke lever position, thank you but I don’t know what you mean by “bush type “ jet, care to expand?

If you go to the FAQ’s section on this site and look for Amal Concentric MK1. Look at the second post from Piquet and that will take you to a very good explanation of the workings of the pilot circuit. Sorry I can’t just post a link for you but not sure how to do that. Maybe someone else can help. Good luck.
