Re: Idling/stalling problem
You might try the Mexican Tune Up.
Rev it to about 2500, put your hand or a CLEAN rag over the top of the carburetor. Completely choke it off so it dies - hold it there till it stops.
It'll be hard to re-start - flooded - but get it going again.
Repeat one more time.
The vacuum generated by doing that sucks water and dirt out of the tiny passages. It's kinda like blowing your nose hard!
Doesn't always work, but if something is clogged it will. Worth a try, and cheap and easy.
Readjust idle mixture and idle speed screws after that.
