Engine is now running, sort of. Starts OK, but can't hold an idle. So I've started following the steps in my copy of the "Operating, Maintenance and Service Handbook", and I've noticed a problem with one of the two mixture adjusting screws. The one in front (on the right if you're facing the side of the engine) adjusted fine. The one in back, though, isn't adjusting anything, because one of the metal arms is bent back, so the screw is slipping off, rather than applying pressure as it's being turned.

Obviously, I need, at a minimum, a proper manual, but I'm wondering if this is a common problem and if I can just bend the arm back. Or do I need to replace the part? Photo of the area in question is attached, but I couldn't get this camera close enough to actually demonstrate the problem.

For the record, I had to completely extract both items, the link rod and the metal piece from the throttle linkage, in order to hook them up. There just wasn't enough room to manoeuver otherwise. Thanks to George and William for their advice.

Yes this is correct, put a drop of lubricant on the ball , you should be able to push the spring in with the ball, if not, use a small screwdriver to push it in as you enter the ball.

Here is a photo with the piece that I failed to describe correctly: https://dl.dropbox.com/u/18543910/IMG_1321.jpg

Unfortunately, in the photo, it's partly obscured by a green wire. The piece is currently attached to the throttle, and probably needs to be pushed into an opening in the link rod. However, inside the rod appears to be a spring-loaded piece that I need to get out of the way that will then hold the ball-shaped piece in place. I think I'm just hoping someone can confirm this, and I'll have to figure out how to do all that with the limited space I have.

I've uploaded the image, hopefully that will work. The 'ball' hooks near to the bottom of the link rod that is dangling from the linkage I've highlighted in the picture.

Correct about the spring, thanks.

Rick for some reason that link does not work. I believe that the spring you are speaking of is to make sure the throttle closes-right? If so There should be a tab or bracket that mounts on the oil filter housing that the rather long spring attaches to. Not sure what round ball you are talking about.

I am now paying the price for taking too long to finish certain tasks. I've cleaned and repaired both carburetors, but now I'm having trouble reassembling the throttle control linkage. The throttle connects via a round ball that (I believe) snaps into a spring-controlled gap in the link rod. I'm having trouble, though, getting the two to stay connected. Any tricks to the process? The shop manual shows how to set the throttle control linkage, but now how to hook it up.

I've highlighted the part in the following image: https://dl.dropbox.com/u/18543910/IMG_1318.JPG.

I also confess to not recalling where the spring connects to the engine block :-(

Any help would be much appreciated.

With the help of the manual, got the whole (rear-most of the two) carburetor off. Not sure if I've got the terminology right, but the I can't get the jet out. It appears to be seized, which would explain why the adjusting screw had no effect and got bent out of shape. Soaking now in anti-seize fluid, will wait a while before trying again to get it out.
