I have always left fuel in my tanks over the winter , mixed gas / straight gas....ethanol / non ethanol , never ever had a fuel problem. Im 55 years old, needless to say, ive been doing that for a long long time.
Coil?

Responses like this are about as useful to any one as Chuck Norris endorsing a fitness machine that does not work.
As has been stated thousands of times there are so many factors that go into determining weather fuel goes off or not in a particular situation that a single persons experiences are not applicable to any one but them, their mower in their shed using the fuel they buy.
And you are obviously one of the lucky ones that can get away with it
I make about $ 30,000 a year from the unlucky ones who can not get away with improper fuel storeage.
People like myself who see better than 100 mowers a year that have been stored in all sorts of situations using all sorts of fuel ALL say the same thing.
Tip the fuel out & run dry or fill the tank to the brim.
We don't say this for the fun of it we say it because it WORKS FOR EVERY MACHINE , EVERY FUEL & EVERY STORAGE situation.
And yes every spark ignited engine has a coil, unless it has a 30,000 Volt power supply.

I have a Kohler V twin on a walk behind mower ( sorry, just don't know the model) which acted the way you describe. It has 2 coils (magnetos). When the engine came to temperature, it warmed the coils sufficiently that the "tired" coil's resistance changed enough to cause it to malfunction and not generate spark power. The engine would continue to run on its other "good" coil but since operating/firing on only one of the two pistons, it had not enough power to mow and travel and would conk out when the blades were engaged. New coil fixed the problem. My 1995 F-350 dump truck with Windsor 305 engine did the same thing and a new coil cured that as well. Keep in mind that as electrical circuits and/or wires heat up, their resistance increases and efficiency / conductivity decreases because the electrical energy converts into heat energy and rapidly increases the coil's temperature and further decreases its conductivity. I am not certain, but I surmise that an out of operating range heated metal object, like a wire bobbin found in an ignition coil, has a lot of electrons zooming around in a random / disorganized manner and an otherwise straight through running current joins the fray since it meets up with the crazy electrons which are resistant to an organized flow. An organized flow is the current on which the spark plug's operation depends. The engine "acts like it's not getting gas" because it is starved for current. It is not sparking sufficiently to sustain useful power generating combustion and then sparks so little as to cause it to shut down. After a period of cooling off, that minute you wrote about, the coil likely cooled off enough to again provide sufficient organized electron flow=ignition current.
Having said all that, the fuel vent failure comment is also a strong contending concept and easier to prove out that changing a coil, cheaper too.

Mine was the carburetor. I had a helk of a time finding an original. I ended up going with a $25 Chinese one on amazon, runs perfect. Don't forget to check the bowl nut . Mine was loose and spewed gas at startup. Tightened it up and no leaks, Mine also came with the backfire solenoid and wire connector.

NO! Don't tell me it ain't so. You say'n he lied to us?
NO! Don't tell me it ain't so. You say'n he lied to us?
And that's exactly what I'm trying to tell you, sir.
In those 55 years, believe it or not, THINGS HAVE CHANGED. The formulation of gasoline has changed, drastically. The design of fuel breather systems has changed, drastically.
With all due respect... I note that you have moved on from penciling questions onto post cards, which is the way technical answers were sought in 1966. In a similar manner, you need to update your knowledge and practices concerning modern fuels and their effect.
All the best, my friend.
I frequent driving by Chuck's ranch in Navasota. the LoneWolf Ranch, and right across the road is the C-Force water company.
