Riding lawn mower Murray Model 309003x99A

I had my carb replaced by my local maint shop. Now when I activate the blade it backfires every few min. Can anyone help me with this problem?

If it wasn't doing it before you changed the carb, you have the mixture set too lean. Find the adjustment screw and turn it out a little at a time until it stops backfiring.
