Ran into an acquaintance who was complaining her one year old mower will
not start. Said she drained the gas last winter. Says she put in fresh
gas, new oil, changed plug. Knows to prime it by pushing rubber
button. I suggested cleaning air filter. I do not know brand, other
than she bought it in Home Depot and threw away receipt. It is a high
wheeler. Thoughts from those that know mowers?
First thing first. We have to narrow down whether it's fuel or
electric(spark) problem. Plugs last more than a season. No need to
replace it to begin with. I don't even drain gas for winter. In the
spring it starts with ~3 pulls. Mower is John Deere.
I found this tip on the Briggs site. Their explanation made sense to me but
my results were perfect. Anyway.
They listed a tip to help determine if its a gas supply problem or not.
Remove spark plug, pour 1 teaspoon of fresh gas in the hole and replace the
plug. Re-attach the plug wire. Try and start it. If it starts but then dies
it means you have a fuel supply problem otherwise if it doesn't start its
OK - I did this and my mower started and it has been running fine ever
since. Try it.
Let us know if it works for you.
A teaspoon straight into the cylinder sounds a bit excessive. More likely
to flood it methinks.
Instead, I pull off the air filter, and squirt about half as much
gas into the air intake on the carb. Gives the engine a chance
to run for a while rather than blowing it all out in one belch
(or flooding it).
I've had equipment whose priming circuits didn't work, and this
allowed me to start them.

Chris. I used to work same place your e-mail from. Been a few years though.
As for being excessive, it may be for some mowers, I suppose. It worked like
a charm for me, fixed my problem right away. I was surprised really. Maybe I
got lucky. I got the tip at http://tinyurl.com/ddc7n
To Quote from Briggs - "Remove the spark plug lead and spark plug; pour a
teaspoon of fuel directly into the cylinder; reinsert the spark plug and
lead; start the engine; if it runs for a moment before quitting, overhaul

I had a brand new mower that I only used for one summer. I never
drained the gas and it sat for over 3 yrs. in the garage. Reason it sat
in the garage is because I have a service do my lawn mowing now. Some
how it became known at work that I had this mower and some one showed
an interest in using it because they could not afford one at this time.
I said no problem you can use it until you can afford to buy one your
self. Adding "if I can get it started". I dragged it out of the mess of
my garage and opened the gas tank lid and it was dry. Gas tank had a
lot of white powdery stuff in it. I blew it out with compressed air and
put in gas that I had in the garage. Seems the gas in the tank and
carb. had dried out.
I filled the tank with gas I had in the garage and tried to start it.
It wouldn't start until I shot a couple of squirts of starting fluid
into the air intake. It then did start but would not keep running
unless I kept pushing on the primer button. I kept pushing the primer
button hoping the gas would clean out the varnish left over from the
old gas drying out. The only way it would keep running was to keep
pushing the primer button. Finally thought maybe the gas that I had put
in it from the garage was old gas and yes it was. I went out and bought
new gas. I drained all of the old gas and put in the new gas. Started
it and kept pushing the primer button. After several minutes it did
start to run on it's own.

Please post a photo of this mower and we will tell you precisely what
is wrong with it.
If you want detailed repair instructions, take the entire mower and
engine apart, and photograph each and every part and upload them.
However, you must photograph EVERY part, even all the bolts..
Thank You for your call !
