No. If you are REALLY worried, fog the motor as is runs out of fuel.

 

Won't hurt it, chainsaws get run out of gas all the time.

 

I tend to agree. I have run out of fuel on chainsaws, lawn mowers, weed eaters and many other kinds of 2-strokes, and have never seen any damage. They come to a complete stop within a second or so after they run out of fuel, so I really don't believe that there will be a lack of lubrication during those last, few revolutions.

 

If it was harmful my weedeater would have died years ago. It's been running fine for going on 9 years and I usually run it til it runs out of gas and stops .

 

Not really good to run them out of fuel....usually they lean out and go into an uncontrolled "runaway" idle. Good suggestion to fog it AND shut the fuel off as that lubricates the entire engine and prevents corrosion.

 

I run all of my Stihl stuff out of gas when they go into winter or any other type of storage. Never had a problem. I worry more about running lean with fuel injection not carbed stuff.

 

the amount of OIL left in the motor itself will lube it as you run the carb dry ... :yes: premix always leaves residue on internal parts
NO it won't hurt it to run it out of gas

 

:noway: nothing to worry about enough oil is left to lub it for next use :yes:

I run all my two stroke stuff out of fuel. Thats when I know it is time to quite and get a beer :beers: before refueling or putting it away :hurray: until next time I need to use it. :yes:
I have a two stroke weedeater engine that has been on the shelf for better than three years. I pulled it down last weekend pulled the rope and the motor rotated just fine. put it back on the shelf, thunk about it, got it back down pulled plug, put a small amount oil in it pulled rope a couple of times and put it back on the shelf. I might need it some day.

 

Ok, I just remember as a kid owning mopeds with people warning me to "not let them run out of gas, it's not good for them".....

 

They probably meant that it wasn't good for the rider as pedaling a Moped is not fun
I agree with the above if running out fuel in a 2 stroke was bad, I would have ruined a few yard tools myself.

 

My weed trimmer instruction manual indicates that running it out of fuel is the method for seasonal storage. Should be no issue.

 

what kind of lawn mower has a 2 stroke? All I've ever seen is 4 stroke B&S.

 

i can't remember the brand name, but there used to be (about 20 years ago) a funny looking green push lawn mower that had a 2 stroke motor on it. the exit for the cut grass was in front of the right front wheel.. watching my old neighbors mow with theirs as a kid was funny- there was always a nice cloud following them everywhere the old guy went, and he was covered with an oily film when he was done.

 

I still use a 2-stroke Toro snow blower, circa 1977. I always run it dry at the end of the season and all is good next time out. If I don't run it dry I always have issues starting it the next season.

The fact that it is still in service after all these decades says that running it dry (that is, running it until it is out of fuel) does not hurt it. Now if you want to keep cranking and cranking it endlessly it after it has run dry, well that might lead to eventual problems.

 

that's the one..
apparently, they still make 2 stroke mowers. i wonder how they get them to pass all the smog regs that are being put on small engines like that...

Running a 2-stroke out of fuel is theoreticly bad. The bottom end will be fine because of the oil left over but it creates an extreme lean condition in the top end. Unlike a 4-stroke which usually dies as soon as it's out of gass a 2-stroke will tend to rev uncontrolably for a few seconds. But, I have ran out of fuel a few times on 2-stroke engines without any problems (everyone has). Why not just drain the tank, lines, and fuel bowl? Same result but with no motor risk. Don't tell the mover guy's.

 

Thanx to all for the replies.

I ended up just dumping the gas out of the jug and leaving the lid off to air out.

I then tried starting it but it won't, seems you have to "prime" it first.....so I don't think there's any fuel in the primer lines.
