Another way to test for an air seal is to but your mouth over the air nossel and blow as hard as you can, remember to have your gearbox assembled when you do this.

That would be an inferior way to check compression.At best you could test the airnozzle for leaks as it would be extended as far forward as it can go.The piston would be in its furthest forward position,thus covering the airnozzle stem from the inside of the cylinder.Far better to actually employ the parts as there intended to move than resorting to static testing.

Alright cool, Ill take note of that. Thanks...
