Check out the 'bolt' that holds the float bowl on. I am thinking that
engine has a hole in the end and also a very small hole on the side. That
hole on the side is very small and hard to see, not the great big one near
Yep, I've read the manual and watched a zillion youtubes.
Got all the tiny holes I could find. Pumped a can of carb cleaner
The gas tank is very clean inside as was the carburetor.
I've rebuilt a dozen auto carbs and motorcycle carbs over the years.
Never did find anything wrong with any of them, but they worked after
reassembly. Until now.
I'd take the bolt/jet that hold the bowl on the bottom of carb off
and let some gas run out till you are sure there is no fuel delivery
problem to that point. Be sure the cap is venting properly. I've been
finding a lot of water in mower gas tanks and carbs (including mine).
Like others said only 100% gasoline in the small engines. Adjust the
valves, it's not that hard to do. You should also be able to keep it
running by taking off the air cleaner and choking it a bit with you
finger to keep it running until it warms up. These things are like
playing amusical instrument. Stay after it.. check the cables and make
sure the safety brake isn't dragging. If you want to try it you might
try finding a jet/carb bolt with larger jetting or very and I mean very
very slightly make the jets a little bit bigger using a welding torch
cleaner although that isn't supposed to be done or needed. Best advice
I know is be sure to use only 100% gasoline. I once had a weird one,
the spark was jumping to ground because of a cracked coil, but it would
fire and almost run. Sometimes for whatever reason a good old spark plug
works better than a brand new one. Don't give up... just one more pull
on the rope and if the rope breaks... well fix that also.
I bought a used mower with similar symptoms and it had water in the
carburetor bowl. Drained it out and it ran great. Then it started
doing it again and I found more water in the bowl, must have come from
the tank. This happened a couple more times before all the water
seemed to finally be gone.

I turned it upside down and got out all I could from the tank. Put in
new fuel. Somehow there was still water trapped somewhere in the thing
and even with new fuel, from the same little tank I use for my regular
mower that never has this problem so I'm pretty sure it wasn't water
from the new fuel. The nice thing about the mower was that you could
undo the fuel bowl with an adjustable wrench and the "nut" also had
the "jet" in it and you could blow that out too. I've also found it
to get clogged with crap occasionally. I used to have a mower that
had a spring loaded drain valve on the bottom of the fuel bowl...I'm
sure that would be illegal today.
I've never had much success, upside down
draining mower gas tanks. Strange design.
Also seen the spring loaded drain valves.
Likely illegal, makes too much sense.
Just think of all the dead baby seals....

I never had much success rinsing debris out of my old garden sprayer
that way. It would be presumptuous to call the designer an idiot when
he probably just didn't. The new tank rinses better.
Draining is the way to go for water in a tank. If there's no stopcock, I
use needlenose visegrips. A peanut butter jar will probably be more than
enough. When you scoop the peanut butter out, leave a note on the
counter reminding you to dump the gas before you put the peanut butter
On the motorcycles I remember, removing float bowls worked very well.
In one case, I had only to flip a wire bail. You can examine what's in
there and dispose of it as you wish.
In small engines with hole in the bowl, you get gas on your hands. You
can't see how much fuel was in it, and you can't check for water or debris.
On my riding mower, when I suspect debris in the bowl, I have to remove
the carburetor because I can't get to the nut on the bowl. The nut is
probably inaccessible for safety because the carburetor sits over the
muffler. It should cool to a safe temperature during the 72 hours it
takes me to get the carburetor off.
Cars, other vehicles, and small engines used to have glass bowls to
catch water and debris. There are still water traps, but you just have
to open the drain because they aren't transparent.
