Sounds like you may be leaking raw gas into the intake while it's sitting. Could be float adjustment or something else. Let it sit for 20 minutes and remove the breather and look in the throat to see if you can see gas leaking or smell it.

Check you choke adjustment. It shouldn't close too tight while sitting for 20 minutes. If it's off, adjust it so that it barely closes when the engine is cold. Here in Texas, I back it off ever so slightly after I do this adjustment.
