Have you disconnected the throttle linkage when adjusting the idle? Perhaps it's set too tight and not allowing the throttle position to drop back to it's proper resting spot.

Has someone been inside the pump for any reason? Most likely it's a throttle indexing problem then.

Can you take a snapshot of it ?

You are looking at the one in the back near the head, right ? Circled in red here.

Is there a return spring on the throttle lever? With the throttle linkage disconnected can you push the throttle lever back against the stop?

Sounds like it may be an internal issue, poor indexing on the throttle lever, or maybe the gov spring was installed incorrectly, or other internal issues?
