MZ/MuZ Riders

Hi, OK eventually got another MZ and is a very fine looking Melon Yellow SX. The original exaust has been replaced with a Sebring which is basically a straight through pipe with the minimum of baffle surrounding it.
The exhaust is very loud and although a bit annoying keeps people from jumping out in front of me (I commute across a busy city) so have decided to keep it on. I have noticed tho' that the bike runs a little rich and never needs any choke on startup and also tends to die if you give the trottle a quick blip. I'm going to have a fiddle with the carb this weekend and was wondering if anyone has made the adjusments to improve the mixture with any success (idle mixture screw and circlip needle position).

Regards from a rainy UK.

Stretchy.

Hate to answer my own question but............

I moved the circlip on the needle to the middle position (of 6) and seems to have done the trick.

Regards from a sunny (at last!) U.K.
