If you didn’t change anything else when you pulled the carb, sounds like you now have a carb problem for sure. Who rebuilt the carb, and what info did they provide?
My experience with electronic ignitions is either they work or they don’t. Doesn’t mean the timing is correct (mechanical and vacuum). And could be a failing coil (weak spark, only apparent under load). But I think your ohm reading is close enough that doubtful.
Unfortunately, it’s going to be more difficult to troubleshoot now, as there’s a new problem. Almost certainly the carb.
