I have received my new carb.

P&P took les than 12hours. Incredible!!!!!
Will fix this one today. But the low end screw in this new one is so much more inbeded, orings seems to be bigger or unused.
This was in my opinion the main problem. Oring was to lose that is why I have lost the screw. So keep eye on them or it will cost you some pocket money and time[]!!!!!!!!!!

regards to all!!!!!!!!!
