air - fuel mixture ?

My bad. Screwing IN the idle air screw makes the mixture RICH. Sorry for the mistake guys, I had a brain fart.
 
Thanks for your fabulous information and pictures. I think with that I will solve the problems. BR Stefan
 
...another question: I have two different needles and needle housings and I am not sure which is the right for my Tilloston, please take a look at the picture; it is measured in cm...

Does this combination needs a special ignition timing???

Hi all,

I found the main problem, the float bowl has been soft solded.

The weight of the bowl therefore was different. I should have thought about it before.
