Husqvarna chainsaw carburetor adjustment tool Answered

i just worked on a Husqvarna 142 chainsaw for a friend. Yes, there are openings in the side of the machine so the Low and High carburetor screws can be adjusted, but a special tool is required, or parts need to be removed from the saw so the screw shanks can be grasped with a pair of needle nose pliers.

A special tool is svailable for about $6 US. It fits over the longitudinal ridges on the upper part of the screw shank. I discovered the right size of semi-rigid plastic tubing makes an effective adjustment tool. Just cut a length three or four inches long. Push one end onto the desired screw shank and turn to adjust. The tubing is rigid enough that it does not twist, but turns the screw needing adjustment.

Good thinking i have done the same also you i could use a 1/4" copper line and smash one side a little bit about half moon will do to fit round the safety screw to catch and turn it to adjust the carb works well also.

Thank you for the suggestion about the copper tubing. If the saw were mine and no longer under warranty I would cut screw slots in the top of the screws. Since posting this, we have purchased a new Troy-Bilt string trimmer with another style of screw designed to foil the owner/mechanic. Its screws have a flat side. I have been sble to make a tool, but I had to use a metal lathe and a welder. For most of my life those things were not svailable to me and are not now available to most people.
