thank you, applied silicone grease and slowly turned the screw in, middle one got out using a good screwdriver which fits the slot perfectly, applied silicone grease also and got it back, adjected the bodies, seems fine now, will see how it works on road. didn't need to touch the left painted screw.

I haven't touched the painted (left) one, but 2 others are really hard to turn.

Need some advice please, Was trying to sync throttle bodies, but didn't touch the left painted screw, middle was kind of fine turning easily around 180-270 degrees easily, and stiff after, but was in sync with the left one in this range. But the right one was very stiff, I thought maybe corrosion, ordered a new screw set and got the old one out (the screw head got really damaged by doing that as the screw was very tight). tried the new one and it is also very stiff going in. Am I doing something wrong? Why screws are so tight?
