Hi all, just rebuilding my Frontera 152 engine, I'm using the Inmotion Italkit piston and crank set, new rod too. There are two piston rings - a chrome one and a black one. Which one is the upper and which is the lower?

I've emailed Inmotion but sounds like he's super busy... and can't reply before Tuesday anyway... just trying to get a headstart. Ta.

 

 

The chrome is the top ring.  The iron is the lower or second ring.

The top ring is also the widest one as well. Bottom one is narrower.
