Default Basic Chain Question

Hey folks - I snapped the drive chain off my 2-stroke bike engine, and am having a hard time finding a replacement chain that fits the smaller engine sprocket.

I ordered a 415 - which fit the back sprocket well - but would not smoothly rotate around the engine drive sprocket. I then ordered a 410z chain (not sure if the z matters...) and that one also fits the back sprocket well, but seems too small for the engine sprocket. I'm like...what the H?

I can't give you the exact engine make - but it's a garden variety 80cc 2 stroke motor that comes in the standard kit that is available everywhere online. I am super surprised I'm having such a hard time finding a chain that fits both sprockets. Help!
