While the exhaust valve stuck open makes sense for the unburnt fuel to
come out, does it also make sense that I'm pulling the cord against an
all but locked engine? I can pull it slowly, as if compression is
leaking down. Seems reasonable that if either valve were open I
should be able to spin it easily.

I have taken one apart, but it was years ago, and at my age memory is
unreliable. That one wouldn't start, but pulled easily, and when I
got it open I found the circular piece that connects the bottom of the
piston to the crankshaft had broken in pieces. I've also rebuilt
several automotive carburetors, but they were even more decades ago.

A stuck carburetor float would account for the extra gas - would it
also account for the heavy resistance? If so, it's worth taking apart
to see. But if there are two separate things broken it's probably not
worth the effort.

A stuck valve wouldnt put in enough gas to squirt out, hard pulling
indicated the cilinder and oil have gasolene in them, it happened to a
friend we removed the plug and gas squirted out 15ft, look into
thecarb issue first see if oil has gas in it


Along with all the good advice you have been given, be very careful of fire.
Excess gasoline and sparks from the ignition should not be allowed together.
Even the fumes can ignite from a loose spark plug cable or removed spark
plug.

It does sound like your cylinder is full of gas and there is very likely gas
in the oil. The engine should rotate freely with the spark plug out and the
blade brake released by pulling the stop lever against the handle.

lawnmower - won't start, spills gas when pull starting
 

It's an old mower that was given to me. The cap says unleaded gas,
the manual says four stroke, so I didn't use premix.

Tank was dry, I put in gas, when I yank the starter cord it's like I'm
pulling against compression and gas squirts out the exhaust. Lots of
it.

Sounds like it's dead and not revivable, but any idea what exactly is
broken?

Perhaps the float in the carburator is stuck open.

It's not dead, it just needs a simple carb repair. The float is stuck open
or sunk or otherwise not closing so gas pours into the engine. Remove the
carb, take it apart, clean, replace gaskets and maybe float/needle/seat as
needed, put it back together. If you don't know how to do this, find a
repair shop if the mower is worth the cost of repair. Maybe find a buddy
that can do this? Otherwise, you might want to just get rid of it if it
isn't worth what it would take to fix.

Fixing the carb is no guarantee there is nothing else wrong. You might spend
a lot of money fixing the carb only to find the engine is blown.

Drain the gas tank. crank it a few times so there is no gas in the engine.
Clean the plug, make sure it is clean and dry. Squirt some starter fluid
into the carb and crank the engine a few times to see if it fires. It should
start up and fire a dozen times or so and then die. If it won't fire with a
clean plug and a squirt of starter fluid in the carb, there is something
else wrong with it besides just the carb.

Then spend some time learning. Come back and ask the question again
after you've read the Time Life book on small engines and small engine
repair, available at your local library. Maybe you'll have a glimmer
of hope of understanding any solutions we give to you.

Yes likely float stuck and now likely the oil is likely full of gas
and soon the cilinder head. Get the gas out, if oil level is up ,
drain oil, and pull spark plug and crank it to see if gas shoots out.
You can remove the carb bowl to see if the float moves up and down.
Dont run it with gas in the oil, it wont lube. Before spending any
money, now with the plug out check to see if you get spark by holding
the plug wire 1/4" from the head with your hand and pull the starter
cord. A minor shock will tell you its getting spark, pull the starter
cord fast and hold tight.

Also, if it has a lever on the handle with a cable going to the engine, you
need to squeeze it. It's an emergency stop.

Have a compression test performed on the engine. An exhaust valve
stuck open would leak un-burnt fuel out the exhaust.

Pass that test, first.

Did that once.
Must have been 19 years old.
more than 40 years later, I say
DON'T DO IT, IT HURTS!

Best to leave the plug lying on the head,
you can see the spark.

this leads to the question what kind of gas is being shot out the exhaust
and what type of weapon is required to perform the operation.
