Shut off and let it run dry after job - or not?

This has probably been discussed many times over here but I would like to get your opinion. I am in the habit of closing the fuel shutoff valve and letting the engine run until it uses all the gas left in the carb until it dies after I am done clearing snow. This has worked well most of the time. I say most of the time because there have been a couple of occasions where I have had no-starts. So is it better to run it dry or not?

it really doesn't matter. Unless you plan on letting non-stabilized/treated fuel in the carb for a long time (6+ months) Otherwise, do whatever you want. It won't prolong the life or give you any advantages.

My fuel is all with Stabil and Seafoam, never run out any machine Ö never had a gas issue in all my life.

I only run non-ethanol fuel, no stabilizer and don't run dry until the end of the season. Never a problem.

I only do it with my genset every time because I exercise it just once per month in the winter. With my snowblower and lawn mower, I will do it at the end of the season and then drain the bowl. Like Oneacer, my fuel is on a similar medication regimen (LOL). I have also hopped on the MOGAS/E0 bandwagon which virtually eliminates the need to do this altogether IMHO.

I'm the same as the OP....turn off the fuel value and let it run out on it's own time. I usually start my machine about every other month in the summer, which also allows me to clean all the dust bunnies that have blown into the garage...

I think it's a good idea to add some cleaner in with the Stabil with the finicky carbs today and keep the older ones clean, I use Star Tron.


Personally I think letting it run dry after each use is a waste of fuel.

I'm in the "run it dry after use" camp. The reason is that it may be months before I start it again, in which time the carburetor bowl is exposed to open air, the fuel can turn to gunk in that time, with or without stabilizer. At end of season I go even further and drain the entire fuel system including the carburetor bowl.

As for the "waste of fuel" argument. Seriously? We're talking maybe a thimbleful of gas, my budget can handle that pretty easily.

And yup, no issues starting again, even several years later.

Ditto! Alcohol attracts water so, an empty bowl is a friend to your carb. Sure, you could run non alcohol fuel but it's a pain in the butt to keep enough on hand. Plus it's way more expensive than Reg gas so where is the loss?

Iím pretty lucky to have 3-4 gas stations within 5 miles that have 0% ethanol. Itís only about $0.30 cents more per gallon so over the course of a year Iím only out a couple dollars. Way cheaper than tru fuel, good grief. Sounds like others arenít as lucky on the no-ethanol stations. I feel like they have crept back up over the past 4-5 years after being a desert for quite awhile.
