I can not get the throttle to adjust properly on a homelite timberman 45 chainsaw. It will not adjust down. The chain rotates at high speed at idle speed. I tried adjusting throttle screw does not change anything.

I also had this same issue with my timberman45. Your comments helped. I had to shorten the throttle cable housing carfully with a sharp knife. Both ends of the cable were screwed all the way on and yet the cable housing was too long. This saw is a few years old now. My opinion is the cable housing is lengthening over time due to incompatibility with heat/gasoline/oil. Eventually the cable will have to be replaced if my theory is correct.

Thanks for the post. Saved myself a trip to the service center with my "new" saw.

Wow! Your idea just helped me fix my Ryobi PCN4545.

It was racing away no matter what I did to the idle adjustment and I had tried everything else. A few minutes ago I disconnected the throttle cable from the trigger/handle end and now, after getting the idle screw back to where it started, it is purring as smooth as ever.

Thanks for the idea Mike.

Hi Brett, I've had the same issue for a month now. I finally got some time to trouble shoot today and I figured out my dilemma after spending about 6 straight hours. I've had the Timberman 45 18" for a year before this started. For me, Everything pointed to the throttle cable length being too short. Hmmm.... Don't cables usually stretch? you ask. I'm guessing vibration had something to do with the readjustment. Most of the screw heads on the saw are slotted/Torx so the tools you will need: Large regular screwdriver or the universal wrench that came with it or a socket wrench w/Torx T-25 bit. If you take off the top cover (3 screws)and the left side of the handle by the throttle trigger(3 screws, 2 differentlengths) you will be able to see where both ends of the throttle cable housing and cable ends are contained. One behind the carburetor and the other behind the trigger. On the ends of the cable housing are white, plastic, rectangular adjustmnet nuts that are threaded onto the cable housing. These could be stripped or loosened, so screw these on tighter to lengthen the cable run. Start with the easy one in the handle. First, slide the trigger assembly off to reveal the cable housing end and cable end. They may pop out at this time but you will be able to see where the ends seat and are retained. Tighten the end as far in as it will go, then reseat it in it's rectangular recess and hold it there while pulling the cable end over to the round recess it seats in. While pulling the cable end watch the throttle lever/stop on the carburetor to see if it rotates away from the idle/stop screw while seating the end in the round hole on the handle. If it moves you need more length. Take the cable end out and pull it back towards the seating hole and eyeball or measure how much distance there is to go before the cable starts to move the throttle lever. You will need to unthread the housing end and strip off that much housing end to gain the distance needed to seat the cable end properly without moving the throttle lever.

The other end behind the carburetor is a little harder to get to so I just stripped the end off of the trigger side and all was good.

If needed, I have posted some pictures on the web to assist in the adjsutments to be made.
