Snowblower Won't Start. Try Gum-Out, Or... ?

Hello:
Tried to get my Ariens (quite Old) snowblower working today, to make sure it runs before actually needing it.
Wouldn't start. All that happens is lots of really dirty, somewhat blue, exhaust comes out. No sounds like it wants to catch. Oil level is fine.
Replaced the plug; no change.
Was wondering -
Is it (most) likely to be a gummed up carb. ?
If so, should I pour a can (or whatever am't is recommended) of Gum-Out into the snowblowers gas tank, and try cranking again ?
Have never used Gum-Out. Is this the way to use it in this situation?
Any other suggestions would be most appreciated.
Thanks, Bob

Did you pour a lot of oil into the spark plug hole last spring, or maybe tip the thing up and let the oil flood into the cyninder area? If it's the latter you might just let it set someplace warm for 24 hrs or so and then try again. Since it's seemingly trying to start, I'd use a couple puffs of starter fluid in the carb air intake & see if that'll blow out the excess oil. Do that OUTDOORS; that stuff is really explosive. And no, don't squirt it into the spark plug opening. Just the carb. If it runs for a second or so, then quits, try it again. Read the directions before using it. Follow them. This assumes it worked when it was put away and that it was properly stored and that the blue smoke is from the plug trying to fire. If you get too much oil buildup on the plug, it won't fire, period, so try letting it set if you tipped it up where the plug opening went downward.

today, to make sure it

exhaust comes out.

Was the unit run dry before storage? The blue smoke sounds like it is firing, but you say "no sounds like it wants to catch". Is it firing? Blue smoke suggests oil burning. Did you use 2 stroke fuel? Tip the unit wrong? Squirt oil in for storage? Have you tried priming it with a little gas in the carb? Checked that the chole is working correctly?

For a prime a squirt of carburetor cleaner into the air intake often gets it going. Often use it in cold weather for balky engines.

Try using premium gasoline in it. I don't know why, but premium seems to work better [than regular] in a slightly gummed up engine until the carb gets cleaned out a little by the fresh gas.
