It might be the coil.

Would vapor-lock also cause a no-spark condition like the OP has?

 

[Rivets]

No, vapor lock would not cause no spark. As stated, bad coil. The coil is either hot shorting to ground or hot opening. Either condition will cause no spark. Solution, replace the coil.

Removing the carb, cleaning, replacing gaskets took care of it for me.
Pull the pin so the float will come off, be careful to watch the seat pin removal and it orientation in the hole. The carb diagram is deceiving.
