What I did with the Rhino like I do on many other small engines is just twist the carb enough to access the bowl.
First drain the bowl using the small screw on the bottom of the bowl (make sure the drain tube is in a container).
Then loosen both clamps on the air intake tubes on either side of the carb and carefully twist it on it's side. Be carefull not to pinch any lines or pull any cables tightly.
Next remove the 4 phillips screws on the bowl, BE CAREFUL and use a proper fitting screwdriver as they strip easy. After the four screws are removed, you need to loosen the carb heater by unplugging the two wires and loosen the large plug just enough to twist the ground bracket so the bowl comes off easily.
Remove each jet carefully one at a time and clean them with some choke and carb cleaner ( GUMOUT® - Carb + Choke Cleaner) then blow them out with compressed air. DON'T use a small wire to clean out the jets, you will scratch the inside, disturbing the fuel flow.
Check the bowl for deposits and clean if necessary, some greenish buildup is common. It's Algae from this ethanol fuel.
Reinstall the bowl and tighten the four screws, tighten the carb heater and ground then reconnect the wires. Turn the carb back up straight and tighten the tube clamps.
Remember, you emptied the bowl so it will take a few seconds of cranking to fill the bowl and start. To prevent furthur fuel clogging, I run Sta-bil Marine Formula (Sta-bil Marine Formula) which is made for Ethanol treatment. I put it in any machine that will have fuel in it for more than 2 weeks.
Sorry I didn't get more pics, it was 30 degrees so I was working quickly. A more thorough overall cleaning of my machine is certainly needed.
