Peugeot Vogue motor assembly

After spending a good few hours trying to stop the new crank from binding i finally fixed the problem by centering the crank in the cases by heating them up and using a mallet to knock it into alignment.
After that, the assembly went really smoothly. I installed the 14/14 dellorto SHA carb and last of all fitted my secondhand variator.
The bike idles very well but isn't jetted correctly so doesn't want to run much above idle. Also the stock engine return spring is too stiff which is limitting variation. Here is a video of the crank turning in the cases, a load of pictures of the rebuild, and a video of the engine running.
