What was Honda thinking when they put that damned philips head screw on the distributor shaft(4cyl) to hold the rotor button on? HOW do you get that out? I even tried an impact screwdriver with no luck.

 

doesnt it have a built-in 8mm head on it?

spray some PB blaster on a qtip and slather it

 

What I wound up having to do one time is to remove the distributor, remove the pieces surrounding the screw and used a pair of vice grips to grab it and turn it about an eighth or a turn each time and then remove the vice grips, put it back on the screw and turn it again, until I can manually take it off.
