first thoughts are that the valve clearances may be too tight, stopping the valves shutting.

So, to cover a list of checks:(if the timing marks align then no further timing worries necessary)

# are push rods straight and in place correctly@
# are v/v clearances ok? (set on the large side to start with)
# is spark strong and repeated?
# is spark plug cap tight?
# is plug wet? replace/clean
# are carb joints complete and in right orientation?
# is carb clean and choke working ok?
# is on/off switch ok?
If you have a second engine then substitution from a working engine can narrow down the troublesome part/s.
Let us know how you get on.
