Won’t start

That should be plenty of spark, although the vid is so short it is hard to see if it's stable. If you cranked it long enough to determine that it does not "come and go" then I'd say that is fine.

Seems to me this thread got a bit off track. If the engine is not firing at all, or at least not firing long enough to "run and die" AKA a couple seconds, you don't really need to worry much about the carb. That wasy my point earlier, I've fired up junk engines for a second or two without a carb at all. Just fuel dumped into the manifold
