Seized T screw?

Hi, my 357xp is idling fast so need to adjust it, but can't seem to turn the screw. Is it possible for it to be this stuck? If so is there a solution? Thanks in advance

I take it you are adjusting the idle screw? The two screws close together are the H & L screws (high and low speed) these should be left alone. The screw you need to adjust is the Idle screw which is a big conical screw compared to the others.

 

It can help sometimes to remove the top cover and ensure the screwdriver is meshing with the screw as it should.

Yeah, not messing with those. Just to confirm I am using a v small flat head screwdriver. I can feel it click in to the grove but cant get it to move. This saw has had several years of heavy forestry use
