So I decided to get around to pulling the carb on a nice 011 that I picked up awhile back, in order to clean the carb out and give it a new diaphragm, which I'm fairly certain is all this saw really needs to make it good as new.
Cleaning and reassembly of the carb went just fine. The old diaphragm was indeed stiff and in need of replacement.
However, trying to get the thing secured back onto the saw has somehow turned into a massive chore. I reversed the process which I used to take the carb off, which is to reattach the fuel line, then the throttle link, followed by carefully fitting it into place.
Here's the part where my problem has somehow developed: The two screws that secure the carb to the body of the saw.
They both screw in without any issue for most of the distance. However, a bit of resistance develops right before the heads of the screws make contact with the carb itself. If I go the final tiny distance to make the screw heads contact the carb, two things happen.
1: The throttle stops working properly. There's a measure of resistance behind the throttle, and It gets "stuck" when the throttle is triggered. Sometimes it'll snap back to its original position after several seconds.
2: The screws are somehow now slightly rotated from their original position before I removed the carb to clean it. You can see in the photo that the air filter no longer fits over them.
Additionally, when I go to back the screws out, the throttle will immediately return to its position if it was stuck. Upon taking the screws all the way out, there's a small amount of metal flakes on the bottom quarter of the threads.
Any ideas on what's going on here would be appreciated. This is one of my most bizarre saw issues that I've encountered yet. I find it hard to believe the screw positions could change so much after just removing the carb once.
