Dropping parts inside a carb on the motor is a recipe for disaster.Did it once many years ago,before I owned magnetic pickup tools.A small screw fell on top of the throttle plates,trying to get it out with needle nose pliers, pushed and opened the throttle plates.Yes, it went down into manifold,could not find it.Had a first hand look at port match.Bottom line for me was a cover anytime the air cleaner is off.
