Bike only runs with choke on!

[Mac_2766]

Hey guys,
I'm having a problem with my 74 CB360, she starts up fine, idles with the choke on, and I can even drive with the choke on, however as soon as I take the choke off it sputters out and dies.. I'm new to this bike maintenance thing, but I'm guessing my carbs might not be working properly?? Any ideas or perspectives on the problem would be greatly appreciated!

What you need to do is locate your idle screw/s and with a screw driver turn them all the way in counting the revolutions make a note 3/4 to 2 1/2 is normal.

Then remove the screw all together being careful not to loose the little spring that may be in there give it all a good clean and replace it, winding it all the way in first then back it out as many turns as you previously counted.

When you screw it in, don't go beyond a "soft seat" so you don't damage it.

What do you mean by soft seat?, Ive been playing with it and it seems to have almost a springy quality when the tension increases, didnt push it because Im scared of breaking it.

Bingo

If you were to keep going you would damage it.
