No spark = no run. Doesn't really require much pressure with a carb. As Root said look for fuel in the window on the front of the carb. should be about 1/2 full. If it just stoped suddenly I'd guess electrical. Check all wires having to do with the distributer. Coils slowly get less effecient not just stop working(I think) You should be able to run on LP if it were a petrol(fuel pump or cloged filter/line) problem anyway. Are you sure there's not a huge vaccume leak somewhere? or a wire dangling that should be connected? Not that a carb rebuild isn't a good idea but that may not be the answer or resolve your problems.
