too many screws

[user 167698]

I tore my Stihl 031AV apart to clean it up and stick a new carburetor, sprocket, and ignition chip in there. That all seemed to go well until it was near fully assembled and I realized I was going to have an extra screw left over. DOH!

I tore it apart again and couldn't figure out where this "extra" screw goes.
I put it all back together and found a screw hole inside the carburetor compartment It looks like it had been used, but I cant figure out what it is used for.

See the picture.
and if this picture isn't good enough, I have some more here: https://photos.app.goo.gl/E98oUu6GKgm7VcjCA
Thanks!

On the older generations of 031 (early and mid), it is another top cover mount screw. The orange tab should go on the inside and screw into that. Just like the 2 in front of that above your carb. Haven’t really worked on the late model 031 much so not sure if they changed it.

Looked at your pick again and your top cover has the tab on it for that screw

Thank you! It almost looks like there is a little orange rubbed off around the screw hole and on the back side of that same hole, on gas tank just behind the on/off switch, there is a little spot where something (a screw?) has been scratching the white paint off. I'll have to get out there tomorrow morning and have a closer look at how the orange plate attaches there or if it even does.

It’s the easy screw to miss cause its up under the handle a little. Usually one of the last i put in cause i forget its there until i have one screw left! If the screw is too long, it could be rubbing the tank on the other side. It should be a normal length screw like all the others on it though. If your av buffers get mushy, it will flex pretty good in there. Had a rubbed through kill switch wire on more than one saw.

I know! It also helps to have a good camera. I took pictures, but honestly, this was my first time working on it and when I was taking it apart, I had to dig through about 1/2 inch of oily sawdust and a lot of cleaning ensued. I bought it new in 1980 to cut firewood. Since then, I've used it for construction as well as cutting roots in my old stump farm and encountered many rocks along the way. The old sprocket was wiped out! Before now, I had never even changed the spark plug, although I've been through 4 bars and many chains.
You've got a good eye for these things. Thanks for sharing your expertise.
