Small Engines (Lawn Mowers, etc.): kawasaki mower, exmark lazer z, push rod

Question
ok maybe you can help i have a 2005 exmark lazer z i had some problems with a bent push rod but i fixed that and now the valves are not set right and i dont know how to set them! can you tell me how the model number on the engine is fd750 if you cant do you know someone that can help!

Answer
Sorry it took so long to respond, I’m in the process of moving and just got internet.  

Have you ever set valves?  Rotate the piston to top-dead-center (TDC) and set both vavles to .004 of an inch.
Which push rod bent?
Let me know if the engine starts.
