Chain keeps breaking?

Hi again guys, I have another question and everyone was so helpful last time I figured I'd ask. Most of our issues with the bike are fixed, and we even threw on a rear rim brake. I managed to ride it around a lot, and it seems fine when running under engine power. But as soon as the clutch is pulled in, there are popping noises every few seconds, and I assume this is attributed to my chain problems. I have posted a pic of the chain breaks, and it is the same exact links every time, the inside link facing towards the spokes. I think this is because the chain running from the sprocket isn't perfectly alligned with the engine sprocket (pic attached), but to fix this we're going to have to move the engine to the left, and the muffler will probably hit the pedals because there isn't much space left (pic attached). Can anyone help me with this problem? Thanks in advance!

I already removed the rubber spacer holding the sprocket to the spokes, the only one left is one the inside, and it looks like flipping the sprocket will bring me too close and the chain will touch the spokes. I'm not sure what dishing the wheel with the spokes is, but it sounds risky and complicated.

Turn the sprocket over, and re-install the rubber piece and you should be good to go.

I'll try it, but it looks like that will give me less alignment between the sprockets than just removing the rubber spacer.

Thanks everyone, I figured it was my allignment. Turns out that since me and my dad had to make custom mounts, they were adjustable, so we pried the engine over and locked the mounts down. So far all our problems have disappeared. Now maybe I can do some riding!

I'm going to keep my fingers crossed, but it seems that since we shifted the engine over the popping noise is gone, and the chain hasn't locked up the wheel yet. But eventually I might get a freewheel kit if I can find a cheap enough one.
