Moin, normally I screw on mopeds (GS 1000G) from the 80’s, but now my wife has got a plastic companion. The scooter is a model from 2002. It is a Keihin carburettor with E-choke installed. What this engine is, no idea. After longer service life went naturally first garnix. New candle pure,Spark is there,but nothing. Ok,then the carburettor has to be cleaned. Oh, you have to degrade everything,in time my carburettor bench 3x expanded. So carburettor ze Re-installed and the box starts. Runs about 1min no longer takes gas and goes out. Fuel is there. Now I thought the E-Choke doesn’t run. So a new one in, exactly the same thing. Now I’ve dropped the plug from the Choke, then the box runs, but of course much too fat. Plugs up again, after 1 min. The spelling turned out 1.5 revolutions. From the feeling I would say fuel is missing, but the float chamber is vol. I don’t know more about Jetz!
