Im not sure as to your mechanical experience but cleaning the carb is one of the simpler tasks or can be . I suggest you check out youtubes selections on small carb overhauls.
It just takes a clean bench ,good carb spray w/tube , safty glasses , patience ,good eyesite and ofcourse a little instruction. just be sure to not loose any part
A funny note 15-20 years ago my mom mowed her yard , and I stopped by for lunch from work . she was upset that the mower quit half way threw mowing. So after lunch I started to take the carb apart and saw the bowl was contaminated , a lawn boy 2 cycle. Mom was early 70's and not mechanically inclined, but had watched every thing I did she was kind of mad I didn't get it running then, but I was going to be late back to work already . when I came home after work the mower was back together , she told me she put it together but she could not get it to start. I looked and it seemed to be OK ,it started fine on the first pull.
