can't post a photo of plugs right now, but by 'fine' I meant dark brown color. I'll post a photo asap.
Also I could've made a mistake, the original main jet was probably 134 or 132, not 128.
I think changing main jets to bigger reduced the choking a little but the difference is so small I may be getting a wrong impression.
By floating level 1mm below floating chamber I meant level of gas in a tube connected to the drain. It's just like some fellows photo in another topic:
I have plastic floats set to around 22mm.
Another thing that just came to my mind is that I had to unscrew my mixture screws to 3 full rotations to get my bike to at least run. the manual says 1,25 rotation. But I guess it's crazy, it shouldn't be like that.
