We have not gone camping now in a year due to illness and
yesterday I took it out for a run to visit with family who
are in a Rehab Facility. Old age is catching up with our
family. Anyways found that I had low power and a vibration
and am assuming it is from STALE gas. The gage shows just
less than 1/2 tank of fuel left. Question is should I just
fill it up with fresh fuel put in some STABIL, or get the
tank drained? I guess I could drive it some more to get the
fuel level lower before filling with fresh gas.

After I got up to speed it ran smooth but when I slowed
down I could feel it vibrating assuming that the plugs may
be fouled. Thanks for any comments. Only way to drain it
would be to take it to a shop and of course replace plugs
etc. Anyone had this problem? Were you successful in
curing the problem. This tells me it is time for me to sell
the rig since it is not being used enough to refill the tank.

Thanks!

Not sure what the correct answer is. I would be tempted to drive it
and then refill it but probably not full. I would put Stabil or
similar in the tank then. Might dump some injector cleaner in there
before driving it.

I would also worry about the brake disks developing high spots due to
rust and the tires. It seems there are a lot of reasons to drive it a
bit... ;-)

It may have some water in it due to wintertime condensation. If
it was me, I'd add a pint of alcohol and then fill it with 93
octane gas.

Fuel injection?
I had a truck once that developed a similar vibration specially at a
certain speed.
I told the mechanic what was happening and he said it was due to a bad
injector.
Takt it to a shop and have them clean the injectors and replace bad ones.

Probably not old fuel. My old Caprice sat for about a year and a half
needing a heater core that I never got around to replacing and it ran
fine when I finally fired it up and took it to the shop.

I had almost the exact symptoms with my little rig after not using it
over the winter. When I lifted the doghouse to see what was up, I
found a huge mouse nest that had partially burned (whew!) and the
insulation chewed off several plug wires.

BTW, this stuff is the catzazz for solving the mouse problem

http://www.tractorsupply.com/en/store/hawkreg%3B-all-weather-bait-chunx-9-lb-pail-of-1-oz-chunx?cm_vc=-10005

Available in the stores in 1.5lb cans. The chunx have a hole through
the center. I strung as many chunx onto a wire as would fit on top of
my air cleaner (carbureted V8) and tied it off to the sides of the air
cleaner. Also put some inside the rig.

It sat about a year before I decided to sell it. This time I checked
under the doghouse BEFORE cranking the engine. Most of the bait was
gone and little skeletons abounded. My cleanup guy said that there
were dead mice all over the inside of the rig too. Good stuff.

One caution: Dogs like the stuff too. One of my neighbors up here
found out the hard way after just tossing a few chunx under his
trailer. An emergency run to the vet ER and a few hundred bux later,
the dog survived. Lesson learned.

Yes, even a Lawnmower, generator, car, truck, boat,or any other gasoline operated engine. I don't consider it a fix. Yes that is my "opinion", but I'm sure you can find reports to say otherwise. :-)

If you need Stabil, you're doing something wrong. My guesses are... not running the gas out of it when stored, not running it often enough, putting stale gas in to begin with, or letting water get into it. YMMV

That is the point. I use it in the gas mix I use for the chainsaw &
weedwhacker because I do not use that much so a small can last a year.
I used it in the MH after our last trip as we have not been doing mid
winter trips because of work schedules so we knew the fuel would be
sitting there for up to 6 months.

What I am not sure would do any good is adding it after 6 months as
the damage is done. That is when I wonder about carbureator/injector
cleaner. If the buildup is not too bad I would think that would work
and be a lot cheaper than tearing down and replacing the dirty pieces.

I have never had a problem with a lawn mower 'cause I use it often
enough to prevent the evaporation of the "light ends".
But I use Stabil in my power washer and it saves me from having to waste
whatever gas is left when I finish power washing.
If you use a gas can that seals completely (one that's approved by the
EPA) the evaporation won't take place and the gas will be good for well
over a year.

I've never had gas problems. How old is the gas ? My first thought after
taking a vehicle out after a bit, add some fresh gas. I would not fill it
up. Add some fuel cleaner, some seafoam, and alcohol if you use high test.
Inspect engine.

Hi Hank, 2004 Georgie Boy with a Vortec 8100 engine on a Workhorse Chassis
it had Stabil in it at the time.

I had Stabil in the gas, what I meant was fill it back up with fresh gas
and
then put more Stabil in as it is supposed also to clean the carb or
injectors
as it goes through the system, that is if I understand it correctly. I was
hoping it would clean the system and restore it to working order. thanks

Stan, I think Lee has the Chevy 8100 (8.1L) engine.

Have a shop check the computer for any codes that may have shown up. Personally, I would have all the plugs changed. At that time they should be able to see if any cylinder is having a problem.

I understand why you would go to the scanner as it will pin things
down faster. OTOH given the storis about rodent damage, etc. Do you
think it would be worth pulling the dog house for a visual inspection?
Maybe start it after fark to check for arcing?

Experience has shown that those two bozos are wrong almost as often as
richard & Jenny.

Experience has also shown that since I started using Stabil in all my
small engines several years ago, all of our lawnmowers, rototillers,
generators, log splitters and especially chainsaws start and run far
more dependably and with less bother than the old run-em-dry method.
Lately I have started squirting some Stabil in the gas tank of our
elderly pickup truck because the inspection dude took note that it only
traveled 250 miles since last year's state inspection.

Yes, I know some people claim to have bad experiences, but I take
comfort in my good results and the FACT that several manufacturers of
small engines recommend the use of fuel stabilizers. Not to mention
that I would not take advice from Hank & nothermark on any subject.

YMMV

Thank you for stating your experience/opinion. However, I have never had a starting issue from bad gas or dirty carb (which Stabil is suppose to prevent). I have never used Stabil, or any other "mechanic in a drum" type fix. I HAVE rebuilt many carbs (motorcycle. lawnmower, chainsaw, and etc.) where the owner stated he used Stabil, seafoam and some other so-called "fixes/preservative".

So what I have gleaned from the replies to the posting below is as follows.
Use Injector Cleaner, or Sea Foam which does the same or if in case it
might be water in the fuel 1 pint of Alcohol to dry it up. And I need a
little
over 37.5 gallons approx 46 gallons of clean fuel I will put in and I
will add
Stabil again in case I do not get it sold right away. If this does not
work or
is not the problem then I will have to take it to the shop and have the tank
dropped and the injectors cleaned or whatever the problem may be.

Thanks one and all for the feedback.

While no one said it I thought that it would be a way to get rid of the
excess
fuel if it turns out that the other cures did not work. If I take it to
a shop it
would probably be part of the service.
