Same question with 420 cc engine, 5 qt. capacity. Thanks, Jack
Dude, fill it up, just carry a gas can with you -- and a watch.
Very difficult to predict something like that, even if it were just idling
the whole time.

If both are idling, the 420 will run out of gas first. Depending on
the snow they are moving, the 342 could run out first.
Is there some reason why it matters?
I switched engines on my 20-something yr old snowblower last winter.
Put a sweet 30 yr old 7 hp on instead of the 8hp it came with. the
gas tank on the 7hp is 1/2 the size of the other. I was sure it would
drive me nuts to have such a small tank-- but a winter and a half
later I'm still using the smaller tank. I fill it about 1/2way
through my driveway/paths.
In the big scheme of how much work there is to moving a few tons of
snow, filling the tank is a minor thing. Same for time taken to do
the job- 2 hours blowing snow- 5 minutes filling tank twice.

It's just that the driveway is over 600' long and on a very steep
hill. I don't want to make one pass and end up with an empty tank at
the bottom of the hill. Perhaps the thing to do is just go 50-100
ft., make four passes and then fill-up. Do it in 50-100 ft. chunks
before filling up each time.
How fast it consumes fuel depends to a large extent on the load.
These engines have governors and with a heavy load the throttle is
going to be open more than with a light load. It's like asking how
far a truck engine will go on a gallon of fuel without knowing whether
it has no cargo and is cruising at 55 on a flat highway or it's
struggling up a steep grade with a full load.
Why not just make a roundtrip down the 600 ft driveway and then check
how much fuel is left. That will give you an idea of when to check it
again.

So run a feed line down the hill from the bulk tank at the top w/ a
gravity-feed dispenser nozzle... :)

If you're running full throttle the whole time as you likely would on a
large driveway the tank will probably last 45 minutes or so. If the snow
is particularly heavy and the engine is working hard perhaps 30 min.
I'd guestimate that you'd probably do ok if you just top the tank off
after each round trip down the driveway and back which would probably be
near the 30 min mark.
The simple solution is to put a larger tank on it. You'll need to
fabricate some mounting brackets, but you shouldn't have any problem
putting a 2.5-5 gallon tank on it. You can find tanks at Northerntool
and others.
that must be right since 42 is the answer to the meaning of life, the
universe, and everything.

Now that we know why- I'd say go with the bigger engine just because
it won't be working as hard as the smaller one. 600 feet is a long
driveway.
I'm just wild-ass-guessing here, but I suspect you can do several
passes in most storms on a tank of gas. Keep an eye on it in
different conditions and you'll likely be able to gas up every 3-4th
pass most of the time.
I'll bet a 6"snowfall at 10degrees will use 1/2 the gas that 6" at 32
degrees will use.
Worst case, I might consider adding some tank capacity-- walking 600'
uphill in a snowstorm isn't fun. [but at least there should be a path
by then.<g>]
For a shot at somebody knowing how long those two engines might run

With that much driveway to keep clean you'll appreciate their
expertise at some point. Are you changing engines, or buying a new
machine?
If you're buying a new machine- you might want to throw your 'specs'
out there [how big and hilly your driveway is- is this your only
snowblower- where you live- what kind of physical shape you're in] and
see if those guys have some suggestions.

Thanks for sharing your knowledge and I'll check out the references
you cited.
This snow blowing will be a new experience. For 33 years, a farmer
with a huge John Deere has plowed the driveway but his prices have
zoomed up, e.g., $225 this past weekend although it was an 18"
snowfall. Total time expended was less than 10 minutes. Also, he
does increasingly sloppy work, e.g., clearing an 8' wide path this
weekend, only 4' of it was on the asphalt. The other 4' was on
dirt/grass.
I'm 65 but active and in good shape. E.g., it takes 5 hrs. to mow the
grass including an hour walking behind a self-propelled hand mower.
Thanks again,
Jack

Put a can of gas at the bottom?
Depends on how hard the engine is running, and whether it is an older
L-head design or an OHV engine.
The 420, all else being equal (which is very seldom the case) should
burn about 23% more fuel and blow 23% more snow than the 342.
If the 420 is not blowing any more snow than the 342, and the 342 is
running at capacity, it COULD burn less fuel.because it would not be
working as hard
Like the old Volkswagens that had the secondary tank. You
ran the main tank out, turned the valve, and then looked for
a gas station, in a hurry.

They used to make in the tank gas gages. Bit of a float, on
a spiral metal that turned the gage. Wonder if those are
still sold. Then, the OP could watch his gas level as he was
working.

are suitable for riding snow throwers, too. Help keep your
feet warm while you're working.

If I remember right from my motorcycle days, there was reserve
fuel in the tank. You would flip the fuel valve 90� from the
normal ON position to gain access to the reserve fuel. I don't
know why lawn equipment manufacturers couldn't do the same thing.
Perhaps a modification is called for utilizing a valve from a
scooter?

The answer is simple: $$$
I don't know of anyone taking a snowblower on cross country trips so I don't
see the big deal. Make a few passes, take a look in the tank and top it off
and you know pretty much all you'll ever need to know. Oh, look at your
watch too so you have a good time estimate.
For a small piece of yard maintenance equipment there would be no need
for such a fuel valve, just push it back to the shed. A large riding
xxxxx is a different story. I would certainly not want to walk back to
the shed to get a gas can when I could flip a valve and drive the
machine back for refueling. The fuel you use to do a job one day may be
more or less depending on the height of the grass or the depth and pack
of the snow. I don't live in snowblower country but I can imagine what
a rump hurt it would be to fiddle with a fuel cap in the snow which
would probably be all over the machine. There are folks who have some
pretty big yards down South, I imagine there are some large yards up
there in snow country too. Heck, I'm lazy, I wanna ride back. *snicker*

Check out the prices of these things:

New ones are well over $200K from what I've been hearing.
Granted, the farmer is just making extra money with his.

Yea, on a 600 foot driveway.
Not.
Heav y enough wire will work. Be tough dragging that #6 cord though.
The design spec for most homeowner equipment is 1 hour run time at full
throttle. Then you have to interpolate from there.
I think only the mfr could give you decent answers to this. You haven't
indicated at what %throttle you want to run them, cold/hot area, loading,
etc. etc. etc.. There are many variables and results can vary widly so there
is no specific answer to your question. On top of that each piece of
equipment can have different run times depending on a host of other things
too.

My father had a '57 VW Beetle so equipped. Never ran out of gas as he
knew to stop in the very first gas station after turning the valve!
