High jet roll pin on walbro adjustment screw

How can I push the roll pin to the other side it seem stuck, may be rusted can it be sprayed with wd40 or something else of course the screw is of the carb
 
Drill a hole in a piece of steel slightly larger then the pin .
If you grind a v slot it should help position it .
Two options tap it completely out from the short side then reinstall.
Tap it through too the other side.
