I have searched and it seems one needs to “press” out the check valve on an HD Tilly, most guides say “press towards carb throat” I believe…

But mine seems to be an odd duck and has a line with holes up the sides on the other side of the check valve that would prevent pressing it out that way.

Anyone know how to remove this check valve? Tillotson HD83a
