The chain popped off during about a 4 block ride today.I was just cruising casually.I ridden the bike 4 or 5 times,the longest trip was 10 blocks or so.Having ridden so many times with no problem it doesn't seem like a chain alignment to me,but I am new to this.The rear sprocket and the chain idler are tight and in same place I assembled them.It's a stinger sd kit in a huffy cranbrook.Any and all thoughts appreciated.

Well get used to it. These bikes seem to think they're your girlfriend now. Lol make sure you carry tools quick links and things like that.

'nuff said.
Hold the bike frame with one hand and pushing as hard as you can, see if the engine or back wheel moves.
Chances are both depending on how you mounted your engine but most likely that Cranbrook coaster brake wheel is shot before the engine is even broke in.
This is very common.

Seems you got that part figured out. Lol
Actually only two things will cause a roller chain to derail. Sprocket alignment and/or tension.
A foreign object getting between the chain and sprocket would be the exception.
Many things might cause one or both to be off; engine or rear wheel moving, sprocket wobble, tensioner not set right or has moved. Etc and etc.
You'll need to do everything you can to assure that the sprockets are aligned and that the chain tension stays between 1/2" to 3/4" of slack. Proper lubrication also plays into this.
