Default Riding Lawn Mower Won't Start -- What to Try Next?

Hi,

I have a MTD (Yard Man) Riding Lawn Mower.

It won't start.

Last year I put it to bed for the winter and started it twice during that
time. The last time I backfired loudly as I turned it off but thought
nothing else of it.

I left it on the battery charger all winter doing a trickle charge.

It won't start.

The engine cranks and cranks but I can't get it to start.

I have checked the battery it is good.

I have a spark from the spark plug.

The fuel is flowing and I had stabalizer in it over the winter.

It just won't turn over. I have also tried starter fluid in the carburator.

Other suggestions?

If not, anyone know anyone in the Markham/Stouffville (outside of Toronto,
Ontario) who does small engine repair on-site? I don't have the means to
take the tractor anywhere right now.

Thanks.

Alan

You backfired loudly?

Check the compression.

How does a novice check the compression? Engines are not really my thing.

Pull the spark plug and use a compression gauge like this one

That is probably a waste of time and I doubt you own a compression gauge.

You don't say what engine you have so I will have to guess an 8-12 HP
Briggs. Backfires are caused by shutting the engine off when it is
running at full throttle. The carb continues to supply fuel/air mix to
the engine but the spark plug is no longer sparking. All that fuel goes
into the hot muffler where it gets ignited - BOOM. Always throttle the
engine down before turning it off and it won't do that.

If it has not run this year then drain the carb, watch for water in the
gas, and refill with fresh fuel (fresh from the gas station, not from
your can from last year.) I'd also put a new spark plug in it.

Most shops will pickup, repair and then deliver the unit back to you.
On-site service is quite expensive and iffy at best. To carry around the
number of parts needed to adequately service everything out there is
prohibitive. This usually results in parts (head gaskets are number one)
being reused when they should not be.

A novice might do a simple rough check by taking the plug out and placing
your thumb tight over the plug hole. You should be able to fell it suck in
on intake and push out on exhaust. Note - make sure the plug wire is
out-of-the-way and not touching you.

But is it getting in to the cylinder ? Is the plug wet when you take it
out ?
If the plug is dry try sealing your lips inside the gas tank opening and
blowing as long and as hard as you can.

My GUESS is you have a burned valve. A compression will be low. The
shop can remove the head, grind the valve seat(s), replace the valve,
oil seals and springs and the head gasket. With the right equipment,
it's only a half hour for them, but it is beyond the scope of a home repair.

Just curious here, what makes you think he has a burnt valve?
