Might be fludding..
If there is a bowl on the carb, pop it off and check the float.. Check for fluid inside the float. If the float is holding any fluid - its bad..
Srpay carb cleaner in there..
Clean the bowl..

Yes its pretty easy you can do it.Are you sure the carb is bad most of them just need a good cleaning .I would disassemble be careful there are some little parts in there and if you are careful and pay attention as you disassemble it you can just clean it .Go to auto parts store get a can of spray carb cleaner .remove bowl be careful the is a float in there a little square or round bellows .Slide the pin out and then the fuel loat pin underneate the float now take out any adjustment screws you can find and spray cleaner in every hole you can find several times and reassemble if idle or fuel mixture screws were removed a standard setting of 1 1/2 turns out from seated position is the norm and some adjustment may be needed once running either in or out till runs smooth.
