hi fellow boaters as the add states ,looking for a 21 case to suit green head valvola or mac 21 in good condition.. i have a case but have snaped a drum screw in the case and cant seem to get it out,, all info and helped welcomed ,, thankyou jason,,
Take a punch, (automatic center punches work well) and hit the end of the broken off screw. This will usually unsieze most screws in a case. Usually after this you can spin it out with an exacto blade if you cant get on it with plyers or your fingers.
If that doesnt work, heat the case around the screw area, then punch it, and try spining it out.
If that doesnt work, go to sears and get their small screw extractor set, drill the screw, get the extractor all set, heat the case up, then try to remove it.
Good luck!
Brian
