my first snowblower....

Well after years of wanting a snowblower, I finally got myself one. Got it used off of kijiji, it's in ok shape except for the tracks, starter, and carb need to be rebuilt. I tracked down a carburetor rebuild kit from a local dealer. It would start when I first bought it but it was to good a deal to pass up.I also found out what was wrong with the starter. One of the mounts was broken, so I carefully drilled and tapped another bolt hole. Turns over good now.
So with some work I got it running good, but it still isn't running smoothly. And today I noticed it's leaking fuel out of the intake valve? And I'm not sure what's going there...the rebuild kit came with a new seat that I did replace. But I'm wondering if it defective or am I missing something?

Oh sorry I forgot to say it's a Tecumseh engine. Not sure of the horsepower though.

What kind of blower? Sounds like you mean the fuel inlet on the carb is leaking and not the engine intake valve. If the seat is new and seated correctly(smooth side toward needle, ridges toward fuel inlet), first troubleshoot to check is make sure the needle was put in correctly. Float installed correctly and not full of fuel (metal) or so old it's saturated (plastic or cork)? Bowl lined up and new gasket?

Well that's another problem I'm having, is identifying the make of this unit. There's no ID tag anywhere on this machine, just the numbers stamped into the engine block giving the engine model number. All I know is it's a 26" 2 stage tracked snowblower, with a Tecumseh engine.
As for the float it's the plastic kind and it's good. I checked for holes and cracks..nothing. also the needle pin,spring, and seat are new....but I had a little trouble putting in the new seat. It turned side ways as I pushed it down. Wonder if I could have nicked it as I turned it the right way? Also is that needle adjustable? Because I blow into the line with the carb upside down and it seems there's a tiny bit of air going though....and when I said the intake was leaking I just meant that's where the fuel is coming out of. And it gets worse when I push on the primer buld? The bowl o-ring is new also, and I'm sure it's installed properly.

Not to cause insult, just asking, but did you remove the old seat? If you did AND the new seat got placed flat and correctly with the needle and float tipped upside down, you should not be able to blow in the inlet ( with mouth type pressure, not compressor type). Some of the plastic floats still have a metal tab to adjust the needle position, some do not. Inverted with the float and needle all correct, the float should be level with the carb body.
Just for an idea here's a carb detail take down. May not be anything like what you have, but should be similar.

Sounds like you're in Canada, eh? Tracked machine with a Tec engine, just guessing Craftsman/Murray/Noma. Look anything like this:

Yup in Canada, Winnipeg accully. Yes I took the old seat out, I'm very knowledgeable with machines. I'm an industrial mechanic at a fiberglass and plastics plant. Just new to snowblowers, and this thing has me frustrated. I still have a ski doo to get running before winter....anyways yes that drawing in the inlet with the seat is exactly what I got...I'll try and get a picture up later of the machine.
