The end with the larger opening goes in first. If you do it the other way you will become part of the "screen smashed accordion style" poster.

I use a long thin punch as a guide when replacing the screen and it slides right in place. In other words, I slide the screen over the punch, then after I get the punch lined up in the engine case the screen just slides in place.
