Either is a part of the same enrichment circuit. Could be either or both.
I would try a Swap of the 30cc front pump & parts with the rear 50cc pump & parts.
If it had TWO 30cc pumps on your carb, would try opening up the Pump Squirter holes by .004 (each hole).
If you have one 30cc pump and a 50cc pump I would do the .004 (each hole) on the Primary first and then
if it needed more pump shot, swap the front pump 30cc parts with the rear 50cc pump parts and try it again.

The pump number is based on 10 strokes so a 30cc pump actually sends 3 ccs of fuel per pump shot and the
50cc pump actually sends 5 ccs of fuel per pump shot
