When ever i have tuned my carb, which has been quite often recently. I start with 2 1/2 to 3 turns out with the a/f screw. From there i adjust the idle screw to where it is almost moving the rear wheel. Then go back to the a/f screw and turn it a little in each direction to see which gives the most rpms. I am by no means a mechanic but this has worked for me.

Still a good idea to have a little seafoam to add to ever gas up.

It is good to know where to start when adjusting the a/f ratio screw, and Alleyoop is the one to ask, but if your having troubles, I think the most important areas to check before that adjustment the a/f is made is, check Vacuum lines, air filter, fuel filter, intake and exhaust for leaks, many times when people are having trouble, the first thing they do is jump to adjust the a/f ratio screw before checking those areas I mentioned  |
