tolltech,

l've ran into this problem many times l would bet money on it, that the fuel line going from the gas tank to the carb is starting to fall apart inside the hose and little pieces of rubber are getting stuck under the needle, on tecumseh 10 hp the fuel line runs between the fan shroud and block which cause it to get hot and the rubber hose to fall apart over time. if u take carb bowl off when it leaks and look inside and u will probally see there's dirt (little rubber pieces) in the bottom of the bowl. u can also add a inline universal fuel filter when u replace the line highly recommended, they have a fuel filter in the tank but it sometimes it gets clogged and people poke at them and break the filter open, then if your tank is at  all dirty it goes right into the carb. that would why when u feed it with water it does'nt leak , but as soon as u hook the fuel line up it leaks right away.

good luck

l assume you mean the crankshat seal ?, if its a deep score l would just sand it smooth with some emery cloth, and it should be fine, when u install the new seal put some silcone around the outside if the seal thin layer is all you need.

yeah l dont see a problem with it, but l agree with underdog there should be a seperate area for it.

underdog,

you could braze it, that would be a permaent fix make sure u remove the shaft before doing so u dont want a fire.

is there any dirt in the bottom of carb bowl when u take it off? if yes clean it and re install the bowl and run engine if possible, then take the carb bowl off again and check for dirt, if dirt is present replace the fuel line going from the tank to the carb, if possible install a universal fuel filter u can get really small ones to fit in tight spaces. the smallest piece of dirt can cause the needle to stay open enough to flood the engine. double check and make sure the choke is opening correctly.
