Does it look really difficult? Should be just two bolts holding it on. It isn't hard and you don't need to understand Bernoulli's principle The most important thing to remember is to take note of where everything you removed goes so you put it back in the right place when you put it all back together. That shouldn't be hard. Be sure to remove and clean the main nozzle and all passageways in the carb. Replace all gaskets with new ones... including the ones on either side of the insulator and the one for the intake pipe. Clean all mating surfaces well.
Might be a good idea to take a pic of the control assembly so you put the spring(s) and arm(s) in the right holes. Oh and clean the outside good before you start cleaning the insides.
Cool mower btw... wish I had one

Are you sure the carb is the problem.What are the symptoms,sometimes it could be a simple vent plugged on the fuel cap.
Make it easy on yourself and buy a spray can of Sea Foam Cleaner and Lube. Take of the air filter and spray everything, especially jets. If the carb has a bowl, remove it and spray. After you get everything clean start 'er up and spray some into the carb. Don't breath the fumes. This stuff really works.
Carb comes off with the air cleaner housing.
A previously mentioned, 2 bolts for the carb and usually a third in the air filter somewhere.
You mobile phone / camera has just become you second best friend.
Every tim you pull a bit off photograph it and the fasteners that held it in place.
Thus when you go to reassemble you will have a step by step photo instruction.
