Those carbs are a pain. Try arousing the idle screw, turun it to the right, then try to see if it will idle. You will have to tinker with the adjustment screw and the idle screw.

You can use a different bolt other than a replacement bolt from the mfg. as long as it's the right diameter, thread pitch, and length. eg: 10x1.25x40 = 10mm dia. x 1.25 thread pitch x 40mm long. The problem usually is that the head on the bolt for that diameter is too small and you'll have to use a washer. That's ok but if the head of the bolt is too tall, the bolt will hit the ground first, keeping the head unit from releasing some trimmer line.

It's probably 50 to 1.
