I had to do some technical things (brake was fixed, fork leaking etc), now the engine comes up. Both cylinders have over 8 bar. It has a top spark of ignition. Even after 8 years the ignition can not have changed. The carburettors are tight. After 10 attempts candles out: are wet, i.e. fuel arrives. The only thing that comes to mind is carburettor out and into the ultrasound, o Although they obviously work. Or does someone have another idea before I get in the annoying carburetor – get out of it? Thanks in advance! Greetings, Uwe
