Three things to check-

1. remove the jet by using a flat head screwdriver and make sure it is clear (i.e. you can see light through it if you hold it up to the sun)

2. the part of the carb where the jet screws onto. if the whole card is the "tree", this is the "trunk" of the tree- there is a hole where gas flows into.

3. make sure the float has no liquid inside it (unlikely for that motor- but you never know)

If there is decent compression, there's no reason why it would not run after checking all of the above.
