I have more than one Diesel engine start and run backwards, gas engines won't do it, but Diesels will. You don't want to run them very long like that because the oil pump is spinning backwards as well.
Piston port two strokes will do that too. I remember being at an Observed Trials and a guy on a Bultaco Sherpa motorcycle had it burp/revese rotation and he came down the hill quicker than he went up it. And as far as the bicycle pedal thing, many of the Italian mopeds(PUCH for one) were started by pedaling them, and you could pedal if going up a steep hill.

EDIT: He is coming back tomorrow to see if we can get it going. I told him I would try to find out the parts the carb needs.

I think it should have the info you will need on this engine. If not, I'll put up a manual that will. There is no key in the flywheel on this model. There is however a means to adjust timing. The engine also has a method of timing advance. These engines were known for bad coils. Does your spark jump at least a 1/4 inch gap outside the cylinder? It should to be strong enough to run. On these models, the suffix F means that it has a flanged output side with holes for a bell housing. The B means that it has a ball bearing on the output side instead of a plain bushing.

What do you mean by 1/4 gap outside the cylinder?
It takes a lot more voltage to fire a plug against compression than it does to fire the plug laying outside the cylinder. By making the gap wider, you can be sure you have enough voltage to fire the plug against compression. If the spark will jump 3/16 to 1/4 inch gap then it should be enough to fire. Also, have you tried a different spark plug?
