Bah! stick this in the repair section. Anyway these carbs are fussy. Get it spotlessly clean, if you've got the float working you should clean out the main jet with an orifice cleaner, this tool is very cheap and available at your local Auto Value. You may also have a clogged exhaust, this can be cleaned by throwing it (the muffler) in a bonfire and letting all the carbon and crap burn out.
