... They produce more than enough heat to vaporize the smoke oil. You only need to be creative if trying to smoke a 2 stroke. 4 strokes have 2 ignitions per every revolution. 2 strokes only have one ignition per revolution. 2 ignitions = twice the heat.

No, This is not true. (its simple to understand that...)
two stroker: the fuel ignites evry time the piston is at the top of the cylinder.
four stroker: the fuel ignites every other time the piston is at the top of the cylinder...
> Therefor, The two stroker produces much more heat then ar normal four stroker.
edit: i also want to add that the four cycle produces more heat made from friction then a two stroker. but this heat is very small part of the total heat. the overall heat production is much bigger on a two stroker
