Default YS91SR check valve

Was fitting my new engine today so in true bloke fashion i opened the check valve to "check" everything was as it should be. Went to screw it back together and butter fingered it onto the desk. Got all the bits but just want to double check how it should go back together.

I have the spring over the collet piece all the way down onto the shoulder with the rubber bit on the end of the spring. ie rubber at opposite end from collet shoulder.

I cant find any exploded diagram of this thing or any pictures of the inside so im kinda stuck.

The pic sucks i just quickly did it on the laptop.

looks right to me.
You may want to pick up a spare or two for the day that you lose a part at the field or drop it in tall grass.
I keep a few stashed here and there.
