stihl br 600 throttle cable question

[clc19chase]

as the blower ages the throttle cable wears and stretches to a point that the carburetor isnt getting full throttle anymore. most stihl equipment has an adjustment to make up for the wear but I cant seem to find an adjustment on the 600 blower. anyone have any suggestions or am I overlooking something. I know a new cable will fix the problem.

In the throttle trigger there is a hole with a screw inside. Use the small orange handled screw driver that came with the blower to tighten it down till the idle starts to change.
