Order a carburetor off eBay. Chinese knockoffs, cost like 10 bucks. Two bolts and you're good to go. Cleaning carburetors is usually a losing proposition. Float bowl starts leaking, main jet clogs again...
I swear the way to go is don't even f*** with it until it's go time. It doesn't start you can blame it on yourself. Nothing worse than doing the right thing and it still doesn't work.
