Thats good news.. sometimes just finding the problem's source is 90% of the problem.
It's not necessary to understand exactly how a carb works to clean it.. (but it helps)
Find some guidance on the general principles of carb cleaning, do's and don'ts .. search this forum and on the net..
prepare a large, clean workspace and label parts as the carb is disconnected, removed and disassembled with masking tape.. or take notes .. and take your time.
