Throttle button is jammed- can't get into throttle only mode

[mhuegli]

Over the weekend, I could not get my 2004 port VP 8.1 engine into throttle only mode. I can't press in the button. Any suggestions on getting this unstuck?

That's going to be a tough one. Need to find the one you have. Below is a link to VP controls
