Hello. My name is Tan.

There is an anti siphon valve at the fuel line connection at the fuel tank.

The primer bulb collapsing is either debris in the tank clogging the pick up tube or the anti-siphon valve sticking closed.

Remove the fuel line from the fuel tank and remove the anti siphon valve. Now check the movement of the check ball does it move freely. Push in on the ball from threaded side of the fitting.
