Default os 55 ax carburetor

Had a mid air a couple of weeks ago, and realized that the carburetor neck was cracked and the retaining screws had fallen off. A small crack is also seen in the crank, where the carb is attached.
Is there any way to fix this or should I replace the engine ? What size / type are the retaining screws ? Size mentioned on carb specs is 3.5 x 5 mm. Could not find any such screws on Tower hobbies OS parts list.

Thanks

If the carb has the crack, replace the carb body.  If the engine is cracked, you may need to replace the crankcase.

This screw will work:

OSMG3840   25081700 CARB SCREW #4D4C2H    US$2.29

These parts can be ordered through any hobby retailer who sells O.S. Max engines and accessories.
