So the chech ball is stuck - in the accelerator pump well. This is the center carb from a 65 gto tripower & Been sitting in the trunk of a rotted goat for at least 16 years, and was last on a running motor in the mid 1980s. Here's what I've tried. Carb cleaner soak 2 days ATF and acetone soak, 3 days. Removed welch plug and a punch to move it from behind Freeze off spray Frozen in freezer a few hours and light heat on carb body with tapping Frozen over night then light heat and tapping None of that has worked. I'm contemplating drilling a hole under the ball??? And now my concern is that if I do get the ball out, what kind of shape is the socket going to be in?
