I was able to get one out once after soaking with a little something and then using the right angle pick of the stiffer variety. You could even grind the tip flat to help keep it from sliding off the needle tip when pushing it back out from inside the chamber. Also I got your nylon washers in the mail today, in an envelope, 1st class to Canada, so however long it takes from N.Y. to Ontario…probably not too long.
