That definitely a good start. Where is the air going though? Coming out a port, or the crankcase?

Yeah, I'm curious about that too... It shouldn't run at all with that much of a leak, unless one of the valves is open. Is that the lowest number that you get, when rotating the engine in the correct direction?

Something is wrong with this leak down test If it has 150 psi in a compression test. A valve must be open or a leak in the line to the head maybe. Make sure it is on top dead center. It is just like adjusting the valves.

Usually, what I do is slowly rotate the engine while cold at least two times with a breaker bar (since there's no ratcheting action), and whatever number is the lowest is your correct leakdown %. Then, you listen to where the air is escaping from, and then you have an idea of what is gone wrong. Just to double check, it's been verified that the clutch isn't slipping? Usually 10-12% is acceptable for leakage.
