Hello, i'm checking my ring end gap and found that the top ring is 0.022 and the 2nd ring has very little gap, almost touching. My piston to wall gap is correct and what i would like to know is wether my piston rings have been packed correctly? Is the thicker ring the 2nd ring? I have taken some pictures so if someone can confirm for me please it would help alot.
The pistons i'm using are 99.5mm

Thanks.

There correct as the photo, you will need to gap your 2nd rings accordingly, you should have some info in with the pistons on this, i think its .004" to .005" for every 25mm of bore dia.

Does the 1st ring gap seem too big at 0.022 though as the piston to bore clearance is good?

What pistons are they ?
For that size bore Mahle piston rings out the box are usually .018" top, .020" 2nd, & the oil rails anywhere from .028" to .040".
