I assume that the cable pulls the throttle lever. In that case, the collar should be pulling on the other end of the lever on the carb toward the bottom of the air box.

I have three of these machines (two run, one is parts) and the throttle is quite different from other Homelites I have. This engine is governed and the throttle trigger overrides the governor to cause the engine to idle when the trigger is released. When the trigger is pulled the cable to the carb box extends and releases the lever on the carb to allow the governor to control engine speed. The picture looks like it should if the trigger is pulled to the maximum speed for cutting and the carb lever should be against the collar and not on the idle screw. There is an air vane in the cooling air flow near the cylinder that is linked to the carb lever. There is a small spring in the carb box which can be seen in the picture hooked in the lever hole. The slot just to the right of there with the screw is the adjustment for that spring. The throttle cable in the picture is not original and the collar has been added. The original arrangement has a stiff wire hook going from the cable end over the throttle lever and pressing on the opposite side of the lever, similar to where the collar is in the picture. There is a fairly stiff spring in the grip handle and some linkage there that causes the trigger to extend and the cable to retract when the trigger is released pulling the lever to the idle position. The trigger and linkage need to be right also before the throttle will behave properly. From the look of it, the governor may have been disabled and the small spring is supposed to now cause the throttle lever to follow the collar. I will take some pictures of the correct arrangement and post them when I can.

sawnami; I thought the same thing, but the collar will not fit behind the lever properly. There isn't enough room.
sweepleader; Thank you for the explanation. I would of never thought that was how it worked. Whenever I reassembled the carburetor into the air box, I had a tough time assembling the governor link into the carburetor lever. Could I have pulled the governor link out of the air vane when I was trying to reassemble it, preventing the lever from working properly?
Thank you for your time, it is really appreciated.

Sorry to be taking so long to get you the promised photos of the linkage, I have not forgotten. I did find that I have an illustrated parts list (IPL) for the brush cutter that I would be happy to email if you don't have one. I have been unable to post it here or I would have. It does show how the original cable looked but the other parts of the linkage are too small, so you need the pictures I have not sent. Message me your email if you want the IPL. Dan

Ok, here are some pictures and after being sorry to have taken so long, now I am sorry to say the pictures are not what I had hoped. New phone/camera, new Windows 10, all screwed up, here they are. You can at least see how the linkage is supposed to be, the little governor spring, the adjuster for governed speed (2 screws), the cotter that holds the governor link with the spring hooked just below, and the throttle cable/wire that loops over the top of the carburetor lever and holds it against the idle screw. I could not get a shot with the throttle trigger pulled, its too far away from where I had to hold the camera. I am quite sure this machine is configured as it left the factory, it is in very near pristine shape. I got some of the parts for this setup off eBay a while ago because the first machine I acquired was all screwed up. I thought I was going to have to repair it until I found this one. Then I found a third one that was also messed up but in better shape than the first, so it will get repaired when I get to it. Good luck and happy XLBC, Dan

Could I have pulled the governor link out of the air vane when I was trying to reassemble it, preventing the lever from working properly? I just reread this last post of yours and realized that I did not address the question you posed about the governor air vane. No, I don't think you could pull the link out but you certainly could have distorted it or other parts inside the rewind housing. All the governor parts seem to be designed to be damaged by handling as they are quite delicate. I would suggest you pull the rewind off and take a look in there. If it doesn't work smoothly without any force, there is likely something bent. It is also subject to the dust and debris that the cooling air carries with it so the vane could be clogged. I would be very interested in hearing how you are doing with it. Dan

Thanks for all of the information sweepleader. I'm glad that I found someone so knowledgeable about these machines because there isn't much info out there. I am currently at work and I will take a look at the rewind housing whenever I get home this evening. The throttle control cable on my machine is a little different than the one shown in the ebay link. I will take a pic and post it later. Sorry for responding to your help so late but other projects are always getting in the way of my hobbies. Thanks again.

The link I gave you is not good anymore, I bought one of the cables he had and it turned out to be bad. He made good on the deal but I still needed a cable. I think I have a way to repair the assembly by replacing the steel cable itself, reusing the original housing and end fitting. Other things have slowed my actual finishing this project but hopefully I will get at it soon and I will pass along what I learn. Dan
