Yup pry marks, if you have a stuck slide Remove the gas from the float bowl then point a hair dryer in at the slide, it will soften the varnish and the slide will come out while it's warm. Then remove the varnish from slide and bore, avoid getting any solvent on the diaphragm. Do not use a heat gun they get too hot.
Wish someone had told ME that hair dryer trick about 10 years ago......
