1) with carb removed to can inspect the cylinder and rings.

2) confirm fuel lines are connected to the primer blub in the right direction. It has a check valve and directional google it.

3) Don't condemn the carb till you are positive fuel supply and lines are good. They are clear enoufh you can tell if fuel flow is good and not getting air in them.

I replaced the fuel lines on a saw a few weeks ago I went to the small engine shop and got 3ft of line that matched my sample. It sounded like your issue and I made every mistake you could make.

Hooked to primer wrong fixed that a no go, in the end I googled it and found the supply line was smaller than the rest, what was happening was the line supply line going into the tank was to big it was pinching it and starving for fuel. I got a smaller line for the supply and its a fix.

In all fuel supply issues I have ran into you could tell fuel supply was a issue from the way the primer felt when you pumped it.
