I have 10 year old Toro 3hp snowblower. It worked fine the first few
times I used it this year.
Last week, it worked fine initially but started to sputter and come
close to dying after about 10 minutes of use. It was much worse when the
snowblower was not engaged with the snow and almost normal when snow was
actually being blown. I managed to operate it this way for an additional
5 minutes and finish my driveway.
A few days ago, the same thing occured only this time it did finally die
after finishing half the driveway without a problem. Impossible to
There's a storm on the way tonight. Any ideas?
Thanks in advance,

Check the usual suspects, spark, etc. Snow blowers often get their air filters
soaking wet and that will shut things down quickly. If you don't have a spare,
dry it out in a 180F degree oven or with a hair dryer keeping in mind that the
plastic parts of the filter could melt somewhere around 221F. Keep a can of
starting fluid handy, clean the spark plug, too. Good luck .
My immediate reaction is change the plug, spray the plug wire with a water
disperser, and if possible drain the gas tank, and check the fuel line to
the carb and refill with fresh gas. A small amount of dry gas couldn't hurt.
Usually what happens with water in your gas is it collects in the carb bowl,
forms a gel like substance and eventually blocks the jets. No gas, no go.
Is there a choke on it? On mine, you need to adjust the choke depending on
the outside ambient temperature and how hot the snowblower motor is. So, on
a cold day you start with the choke full-on but then you need to back it off
as the machine comes up to temperature or you get sputtering and maybe
eventually even a stall.
this sounds like a blower way out of tune. the choke should be used for
nothing more than starting it up in the cold.
if you require choke after the engine has been running for several minutes,
even a little bit of choke, the carb is out
of tune and needs tweaking.
most modern blowers don't have chokes anymore anyway....its all primer :)
sounds like a carb problem bud. you say when blowing snow (under load) the
engine would have run
closer to normal than "unloaded", right? your engine has a load
compensating throttle that "gives er gas"
when becoming loaded. this gas is what kept it running.
I had a similar problem on my old girl...early 80's model 10 hp, 29" cut.
VERY powerful, but one day would
start but not stay running. starting fluid in the carb kept it going enough
to load it up and get it serviced. turned out
to be a pluged main jet...crap built up and finally choked it off
completely. a carb cleaning (not chemical, but disassembly
and manual cleansing) resulted in the best running snowblower I've ever
