Hello, Welcome to Just Answer.

It would seem that the carburetter might be dirty and will need to come of and be cleaned. The fuel is not going into the idle circuit. That is why it will not run on.

This should answer your question should you need more information please do not hesitate to ask.

Please explain the idle circuit. Are there 2 jets. One for idle and another for pumping? How difficult is it to rebuild this carb. I have done one American one before.

Are you still available?

There is a brass bolt on the right hand side of the carb. That is the jet for the idle circuit. You can unscrew the jet and clean it, it might be all you need to do unless the passage why is also clogged. These carbs are pretty simple to work on and do not need a high level of skill to strip and clean. The float level is set with the needle and seat bolt and don't need adjustment, unless the brass plate on the floater is bend. Other than that one must just make sure that there is not a lot of play on the butterfly shaft where it hinge in the casing as this will cause flat spots when accelerating.
