Hi Folks, When I stored my lawnmower last fall, I left a little fuel with
winterizer in it.

I drained the fuel out put in new fuel, primed it several times and tried to
start. I runs for a couple of seconds then stall with white smoke coming out
of the carburetor. If I prime it again it does the same thing.

It's a Quantum Master with a B&S 5.0, several years old.

What can I check for to keep it running ?


Thanks
Dick

If you are starting in the spring, start at step 9. If you are starting in
the fall, start at step 1.


1. Never leave fuel in the mower over winter, even with Stabil or another
fuel treatment. Run it dry, dry, dry before storing.

2. When storing, pull your air cleaner and the fuel line at the tank. Get a
can of pressurized carberator (sp ?) cleaner and spray a bunch into the
fuel line and into the air intake. Pull the motor over several times. It
may even "start" on the carb cleaner. Don't worry about that. You are
trying to get rid of all gas reside in the fuel line and carb so that it
doesn't "gum up" while stored.

3. After you've pulled the motor over a few times, reconnect your fuel line
and reinstall the air filter after you have cleaned the filter.

4. Pull your spark plug and clean it. get the oil and goop off it.
Spray a bunch of carb cleaner in the plug hole. Oil the plug threads
lightly and reinstall the plug loosely and put the plug wire on. Again pull
the motor over several times. So far you have invested maybe 15 minutes if
you are a slow wroker.

5. Safely dispose of all the gas in your gas can. Run it in your car.

6. Pull your blade off and send it out to be serviced, or if you know how,
sharpen it yourself.

7. While the blade is off, thoroughly thoroughly clean all the crud off the
mower deck underside. This is the longest job you'll have, maybe a half
hour. Reinstall sharpened
blade. Put mower to bed for winter.

8. Spring time, buy new gas. Treat with Stabil or similar product.

9. Get new spark plug. Replace old plug. Lightly oil threads before
inserting new plug. Tighten new plug. Attach plug wire, making sure you
have a tight connection at plug.

10. Make sure tank is completely drained. Again pull your air cleaner and
the fuel line at the tank. Get a can of pressurized carberator (sp ?)
cleaner and spray a bunch into the fuel line and into the air intake. Pull
the motor over several times. It may even "start" on the carb cleaner.
Don't worry about that. You are trying to get rid of all gas reside in the
fuel line and carb and any "gum" that might have formed over winter.

11. After you've pulled the motor over a few times, reconnect your fuel
line. Install a new air filter.

12. Fill tank with new gas.

13. Start mower.

Your white smoke symtom says to me very dirty plug, and probably too much
gum in cyinder from old gas. Carb cleaner, carb cleaner, fresh gas, new
plug.

Forgot two steps -- call 'em 9A and 14 A--

9A, Check and top off the oil.

14 A. Right after you run one tank of gas through it in the spring, while
the motor is still hot from that run, drain the old oil and replace with
fresh new oil.

In close to 40 years, I have never had a problem letting a mower just
sit over the winter with fuel in it. However, twice I followed the
religion that requires running it dry in the fall and this resulted in a
carb rebuild because the gasket in the middle with the acceleration pump
had gotten hard or leaked.
