OK after trying universal mounts and traditional mounts , the chain didn't clear as I was warned ABOVE.
After tinkering around more I finally got her running!!!.
I added a 1.5 sprocket adapter(gasbike.net), bent my coaster arm several times to get it right.Plus a occ chopper mount(gasbike.net), That did the trick.
The chain clears the tire , I test rode it to work.
So you moved the whole engine left.
That will work if stays in place, good for you!
Have you done the shove test?
Hold your top bar with one hand, your engine head with the other, and shove the engine back and forth as hard as you can.
If it moves AT ALL, that is a fail.
I am not sure what your final pic is...
One pic has your carb at ~45 degree angle, that will always be a problem.
You will know when it won't start, and the reason will be because the float can't shut off fuel and it will run straight through and pool in the bottom of your engine.
And it looks like your tensioner is on the top (power) side, they are only designed to take up slack on the bottom (return) side.
When that fails it's going to really ruin your day, that is assuming it hasn't already been ruined because you couldn't stop that heavy bike with just that wimpy coaster brake and crash.
Sorry to rain on your parade as you really put a lot of effort into a loosing battle.
In short I suggest you check your medical coverage and ride in full body armor as I wouldn't ride that death trap around the block no matter how 'cool' it looks because I know first hand how 'un-cool' it is to wreck by going faster than brakes, which in your case is about 10mph.
