Dale,

If your hand will fit, you can start that engine by hand. Just snap the rotor against the compression after you prime the engine. Just make sure the engine is set to idle and you can get your fingers out quickly. You will need a new fan. The blades are not separate on the Turbax fans. Just remember to balance your new fan. Personally, I've seen Turbax powered planes fly for year with more damage than that... however I wouldn't trust or recommend it.
