I rencently heard a ticking coming from the head of the motor and when i took the top of the motor off i found the two bolts holding the timing sprocket onto the cam shaft had stripped out and the sprocket itself had cracked and warped. I bought a knew sprocket camshaft and bolts and put everything back together but it wont start. It will turn over but wont start even with starting fluid being sprayed into the air assembly. Is there anything i need to know about how the sprocket liines up with the stroke of the valves or anything thanks

 

idk what is up with that but I would take it to a store to have it done. If you don't want to spend the money i would make sure that u put it on right.

 

The cam/sprocket must be timed .. If it was turned over before it was timed the valve/s are probably bent now...

thank you so much for the diagram. one question though how do you know if the valves are bent.
