Yam 50 2stroke trim question

[Jakey555]

Is my 50 DETO trimming all the way in properly? It's slow to tilt both up and down but is working. I've bled it but this has not improved speed or range. The engine has been stored outside unused for 6 years. Photographs of it trimmed in as far as it will go.
I'll have to try to upload the pics separately below...

Neither phone or computer will let me upload to this site:
I've managed to get the pictures into Google+ though

I don't think it's trimming in fully

Further to this, it's worth pointing out that the main photo
Shows the engine on a vertical frame. Outboard transoms are of course not vertical. So a related question should be 'is it OK for my engine to trim in to about 10 degrees off vertical when mounted on a vertical frame?
