Thnak you  playntraffic the thing is that as you know the carbs in the TH 75 have a spray bar that goes from wall to wall in the carb with a little hole in the middle. Inside that spray bar is where the Idle needle goes and you can see it when you screw it in. All the instructions from tower are wrong and I can not belive that they have not update it after so many years. I  am looking to get the settings in turns. I do not like to guess the initial setting and that is what I am doing now. I did the tunning as per their page but when they say there is no gap I can tell you that either I am not understanding what they mean or that they are wrong. Also the instructions that say that the gap is 3/32 to 1/8 is also wrong because the little hole is not that big so that setting can not be used. That is a setting that can be used in an OS engine where you can see the gap and from the top but not in this one. 
I will keep playing with it but if someone can give me the starting set up in turns I will really appreciate it.

Thank you
