Ariens 920001-ST624E Sno-Thro won't start

Mechanic's Assistant: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

Yes and yes

Mechanic's Assistant: Do you plan on doing the work yourself?

Yes, so far

Mechanic's Assistant: Anything else we should know to help you best?

I'm an engineer, but...I've reread all the start procedures...its worked well for about 8 years....not a ton of use....I always change the oil...I've checked the spark plug for fouling as well as the gap. Oh and I'm careful about fouling the correct starting steps.

Pour a small amount of fuel into the intake or spray the carburetor with starting fluid or carburetor cleaner if it starts briefly the fuel system is the issue

I've got some starting fluid (spray). Can you give me a general description of how to access the carburetor?
Carb is located under or behind the air filter. Remove air filter and pour or spray fuel into the intake

I've looked at (Tecumseh OH195SA) engine and it appears I'll have to remove a few bolts--not a simple latch to access the air filter/carburetor (like on my chain saw). It is below zero so we are done for tonight, but if you wouldn't mind speculating on just a couple next steps....for example: What if it does start and continues to run? Or, what if it starts but peters out like you mentioned above--thereby id'ing the fuel system as the culprit. What is next step there, fuel filter? I've thought about changing out the spark plug, just cuz they are cheap, but it looks pretty good. I cleaned up the electrode (with fine grit sand paper and verified the .30 gap....the first couple threads were pretty black... Thanks in advance, Dave.
If it does start, but dies within a few seconds, the fuel line, filter, carb could be the problem. I would make sure fuel comes from the tank freely if so the carburetor may need to be removed and cleaned.
