25 Years ago and as a 15 Y.O. and not having a good (well, not even basic) understading of carbs and jet turbine engines I faced the dilemma of how to grab a small nut I had dropped down the carb. It was sitting on the top of the butterfly valve and was ready to drop into that black hole of a intake manifold that I so so didnt want it to dissapear into. Long nose pliers? No. Wire and hook it? No. Take it all apart? No. Magnet, No (Not that bright). Any other good suggestions?. YES!!!!. Use mums vacuum cleaner and suck it out! Well since then I know that carbs exposed to a vacuum supply fuel and mums vacuum cleaner has a ignition source (brushes), and vacuum cleaners can creature quite a bit of thrust when the air/fuel ratio is right and there is a igntion source.
