there isn't that many parts when taking one a part
what I do is take carb apart and then blow through every little hole with carb spray and use a fine piece of wire (bread tie with the plastic/paper peeled off it) and run the fine wire through all the little holes then more carb spray then another trip with the wire and repeat as many times as it takes to get it clean.
check the float adjustment
put it back on and go
also check to make sure you've got good fuel in the tank and that it is getting to the carb
there is about a gazillion carb cleaning videos on youtube.com

I'm not sure it those are your exact carb but should be close
looks like brand new china carbs on eBay for about $50
I've bought a couple china carbs for other engines and had good luck with them
