Thanks Pete for these advices!!
I´ll try to find jets close to 115/118 first. I also noticed that float levels were little bit wrong - varying from 8.5mm<->11.5mm, when manual states 7.5mm. This means that fuel level has been too low - unless tang has been bended with purpose to compensate increased float weight? I have noticed sometimes car carbs floats tend to get “wetted”, catching extra weight, and causing too high fuel level and flooding.
SW (Switzerland) models has VD85G carbs and 68kW (92ps) max.power.
Thanks, Sami
