I'm just wondering if running a snow blower in the summer would harm the
engine because of insufficient cooling? It seems to me that you have
much the same kind of Tecumseh or Briggs & Stratton engine on a snow
blower as you do on a rototiller.
Hey! I learned something new. I had no idea that snow blowers had no air
filter. I understand the reason and I wonder if the cooling air flow
over the engine is restricted so the engine can run hot enough for
efficiency? If a homeowner around here possessed a snow blower, it's
sure sign that he is an alien Yankee who moved here with all sorts of
exotic items not see here in Alabamastan which is much closer the the
equator of this planet thus having a warmer climate(usually). Al Gore
changed our climate in order to convince people that they must be taxed
for the utilization and production of one of the basic building blocks
of all life on Earth. ^_^
I don't winterize or summerize any of my outdoor power equipment. Snow
blower, leaf blowers, lawn mower, trimmer, etc. Instead, I start them up
once a month and let them run until they've reached normal operating
I look at it this way: depending on the weather, any one of those items
could easily go 3-4 weeks without being used. If a lawnmower can sit for a
month during summer without being used, then it can sit for a month during
the winter without being used. The same goes in reverse for my snowblower.
I've had more trouble with all the other suggested methods for storing OPE
that I find much easier just to start 'em all once a month. It's been
working for me for about 4 years so I'm sticking with it.
Once a month?
I don't do anything at all.
Stop using it in the fall, start it up in the spring.
I have a 2 cycle string trimmer that I sometimes don't start for a year or 2.
Starts fine when I want to use it.
Who makes up these time wasting rules?
I didn't know it was a rule. I just do what works for me. On those rare
occasions when I've left OPE without starting for full season I've had
problems, so I settled into once a month...more or less. It's not like I
set an alarm or anything. When I'm out doing other things in the yard, I'll
grab a piece of equipment and run it for few minutes. I like being outside,
regardless of the weather, so it's not a big deal.
All of the automatic residential generators I installed exercised once a
week at a time of day determined by how the timer was set. Those
generators ran on natural gas so there was no concern about stale fuel.
It was done to make sure it would be ready for an emergency. I don't
guess there was any emergency need for a snow blower to run at any time
except for this winter. ^_^
I'm 30 years into my mowing business. All my
equipment is left alone <unstarted> for 3-4
months each year. It used to be that I'd not
even drain the fuel at the end of the season, tho
that is no longer the case. No issues whatsoever.
The ethanol and/or overall difference in gas gives me
occasional grief. I've had to pull the carb off of
a thing or two <mower, blower, whatever>. I don't
remember gas 'seperating' in the past, as it does now.
And the ethanol plays a role as well I'd suppose.
Either way, it's pretty easy to just run everything dry
at the end of the season.
I think I know why you feel you've had good results by starting all your
small gas engines one per month.
Small gas engines use splash lubrication. Basically, the crankshaft
splashes oil all over the inside of the crank case, including the
cylinder walls under the piston. It's that oil film that helps to
provide good compression when you start any of your small engines.
Piston rings by themselves don't provide sufficient compression to start
a gasoline engine. Piston rings are smaller than the grooves they ride
in, and that allows some of the hot combustion gasses on the power
stroke to get behind the piston ring and push it outward tightly against
the cylinder wall.
It's the pressure of the hot combustion gasses pushing the compression
ring outward against the cylinder wall that provides the tight seal
needed to get the most power out of the engine. But, until the engine
starts, you have to rely on the oil film on the cylinder walls to help
seal around the compression rings to give the engine sufficient
compression to start.
By starting your engines once a month, you're continually recoating the
cylinder walls with new oil so that the next time the engine is started,
there's still enough oil on the cylinder walls to provide good enough
compression for the engine to start.
You could do the same thing by simply shaking a small gasoline engine
(like a leaf blower or chain saw) immediately before you start it at the
beginning of the season, or taking the spark plug wire off of a
rototiller and pulling the recoil starter a few times just to splash
some oil on the cylinder walls. That is, instead of starting the
engines every month, why not simply do something to splash oil onto the
cylinder walls before you start them for the first time each season.
The idea is simply to re-establish an oil film on the cylinder walls
before trying to start the engine for the first time in the season.
Without doing that, the oil film will drain away over the course of
several months, and it won't be sufficiently thick to provide a good
seal around the compression ring, and you'll have trouble starting the
engine cuz of lack of compression.

I start the generator on the first weekend of every month and let it run to operating temperature, maybe 5 minutes. During the summer I also start the tiller and during the winter the snow blower gets started on generator wakeup weekend.
Merely running the engine off-season is not sufficient.
The auger gearbox and drive mechanism need to be exercised as well so you should also walk it up and down your driveway a half dozen times or so.

Funny thing, I've never seen anything in a snowblower
manual that said you had to to that. I run the fuel
out of mine and leave it all winter. Been doing that
15 years and the only problems I've had were if I
forgot to empty the fuel. Any gearbox has gears that
are covered in oil. What bad is going to come to them?
