(1)There is a rubber seat under the needle--if you blew air into it to clean it you may have forced it out. (2) Shake the float and listen for liquid inside it--it may be leaking and full of gas. Those are two common problems.

You say you replaced the seat. Are you absolutely certain the old one was removed? Are you certain the seat was installed correctly and squarely? Groove-side in first? Even though the float is new, does it have fuel in it? If all the answers to these are positive then you may have a score mark in the seat bore. How did you remove the old seat? With a pick and might possibly have acratched the bore? Such scratch mark will allow fuel to pass by the seat on the outside of it and the only fix would be a new carburetor.

you may want to check the float needle ,its very easy for that to slip out of position during reassembly.

Take your engines' model and spec numbers to your local Tecumseh dealer and they'll set you up with a new carburetor. BTW, I've never heard of too long of a primer line causing a leakage problem and I've worked on thousands of snow carbs in my years but hopefully this is in fact your trouble and I'll have one more oddity to add to my mental service book.

Napa wouldn't be your best bet,if you don't have a local mower shop near you ,you can get a new carb online from Jacks small engines [jackssmallengines.com] ,i gave them all the #s they needed and they sent me the carb in a couple of days.wasn't cheap though.

it sounds to me like the float has a hole in it, that has filled it with gas, which is causing the needle valve to stay open and flood,

take off the float cover and the float, and shake it. if you hear stuff squishing around, then gas is inside and you need a new float.

Tecumseh has a gauge for measuring the proper "level" but you likely don't have one. So, with the carburetor upsidedown the float will be slightly below parallel with the carb body. If you have an 11/64" drill bit, place this between the body and the float (opposite the hinge pin) and the float should just touch it. With your problem, the float would have to be touching the body in order to leak, if it all, that is.

I don't know if this will work with your carb.
I would get a clean hose that fits your fuel inlet.
invert the carb with the float assembled blow lightly into the hose and see if the seat leaks.
if you must, place the carb in water and try the carb in both directions.
