Vicente's input reminded me to mention that I use standard size fuel 
tubing to fill the space between the screw and the engine holes.  I cut 
little sections of the fuel tubing that are the thickness of the engine 
mount.  It centers the screws in the engine mount holes and grabs the 
screw, making it easier to mount the engine.  It also give you a little 
'wiggle room' in making small thrust angle changes.
