Snowblower engine "misses" and fires not consistently

Post by Ignoramus1678 » Sun, 15 Jan 2012 08:36:41



Dragged out my snowblower and I noticed that it skips ignitions and
does not "fire" every time. What could possibly account for this?

Wow, you name it!  Unstable mixture, water in the gas, dirty spark plug,
degraded magneto coil, bad points (if it has them), wrong ignition
timing (can be the shearable key in the flywheel), loose head bolts,
bad valves.  Hmm, can't think of too many more.

46 is still below my *** threshold, and there isn't enough money in
the world to get me to live in CA, much less LA. Been there, did dinner
in Beverly Hills too, ok to visit but that's all.

How old is the gas? Has it been stored under cover, in the dry, or in
damp where water could get into gas. First step is drain any old gas
and put in fresh gas of lowest ethanol content you can find.
 Good idea to drain the carb float bowl too and make sure it is clean.
If the carb is gummed up it will usually run lean - and a lean blower
engine will "hunt". Turn the mixture***out until it settles down
(usually 1/4 turn or so) and put a cleaner in the gas. I'm partial to
SeaFoam, but MMO has been reported to give good results too - likely
take a bit longer from my experience, and a can of SeaFoam and a
bottle of MMO are about the same price,  Once the cleaner has done
it's thing you can turn the***back in to the proper mix.

Maybe it's an older one, with that type of engine. http://www.FoundCollection.com/

35 now in Grass Pants, OR.  It has been 23F this week, some days
warming up to a balmy 40, others to a roasting 50.  We're due for a
cold snap next week.  Time to stock up my pantry, just in case.
That white stuff makes going up the steep hill to town quite a chore
in a 2x2 truck.

The gas is a year old, or more. (I used it last year, but the gas in
the can may have been old even then).

I ran it out of gas yesterday, dumped old gas from the can, and bought
new gas. I will try it on new gas and will report.

My snow blower ran like shit till I replaced the muffler - square inch
hole was feeding exhaust gas to the carb intake. Runs much better now.

How are you storing the blower during the off season? In our clime
(I'm west of you one state), and you can store your lawnmowers over
the winter as the gasoline generally does not evaporate the light
hydro-carbons.  BUT never store chainsaws, snow blowers or any other
tool with gasoline over the summer (unless your using them often), as
you end up with tar (the heavy HCs) in the carburetor.  Even if you
have a gas shutoff, unless you run the fuel bowl dry, you end up with
the fuel jet ports plugged/fowled.
You may end up having to remove the carburetor and soak in cleaner.
Depends on if you don't have a shutoff, and it sat in a storage shed
all summer.

Darn, this was a nice winter until Thursday.  At least it's 6 weeks
later then normal.

I was gonna suggest something like your example when EA was askin' about a
emergency generator.

When I looked them up, there were lots of examples online, of yard machines
and utility equipment run with H&M many years ago.

The larger oil well pumps I've seen around western PA (made in local
foundries), have had spoked cast iron flywheels up to 5 feet in diameter..
many of 'em sitting idle, going to waste.
There are numerous pumps still in use, as close as about 10 miles from the
city, then scattered randomly all over the place.

My front door is wide open, the back door is wide open, and there are 3
windows in the living room open. Not quite warm enough for shorts and a
t shirt, but close.

There is a reason I moved away..far far away from northern Michigan.

Gunner, who in 5 months will have the house tightly shut, the cooler
running full blast and trying to avoid going out when its 112F during
the heat of the day.
