MZ/MuZ Riders

Hello everyone,
I finally repair my mz etz 150 and started riding it. It's great but yesterday after a ride when I get home after some hours it won't start (this was never happened) so I checked the spark and there was spark, but the spark plug was wet so there is gasoline.
When I heat the spark plug, first Kik make some detonation but then again nothing. So I thought that it may be the timing so I try something that I know from Balkan 50 but now I don't have spark at all. Can anyone tell me how to make the timing and what is the possible reason for my problem. Thank you in advance.

Hi Kostadinov,
sorry for the late reply.

The problems you describe can have several reasons, the first that comes to mind is that the fuel valve in your carb leaks, while you left the fuel tap open (or that leaks too). For more info look in the relevant workshop manual on http://www.miraculis.de/aw/download/load.html, which are all in German, or maybe you can find something on Blurredman's FTP site in English.
