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.
Turn the throttle all the way closed as far as it will go, then back out the needle to more, and see if you can close the throttle still more.
Don't force anything.
Once the throttle will not turn close any more, turn the LS needle in up to the point that it stops. Again be gentle. You do not want to score the needle itself.
Now turn it back out about 3.5 - 4 turns. This should leave the low end rich and you should be able to start the engine using a HIGH idle.
Then adjust the HS and finally the LS to get a more reliable lower idle.
