Last poster, is this on a turnaround?
Can I ask how you get the engine past idle to an adequate power setting for HP/IP change over on stand?
The OP was on the technical aspect of the snag post an MEL dispatch, that if time was not available the complete way to go about things. Lock the bloody thing out send it on its way.
Please post a reasonable technical evaluation of the problem not how you would flog it on, I'm sure we can all post that sort of content.
