ULPT Request: How to break a gas powered leaf blower (without it being obvious)?

[u/shadymonger]

Let's make it seem like it broke on its own.

[u/crosstheroom]

Pour water into the gas tank.

[u/jmb00308986 → u/crosstheroom]

Easiest, best, hardest to prove it was sabotaged

[u/NixonsTapeRecorder → u/jmb00308986]

Also very quick and simple to fix

[u/gujwdhufj_ijjpo → u/NixonsTapeRecorder]

Mix some salt in the water. More corrosion.

[u/jmb00308986 → u/NixonsTapeRecorder]

Not if rings get damaged internally

[u/Knight_of_Agatha → u/jmb00308986]

except when...they try to start it and water comes out

[u/jmb00308986 → u/crosstheroom]

Easiest, best, cheapest, and hardest to prove it was sabotaged

Depends on what you mean by break it. Like keep it from running in the hands of someone who is mechanically declined or have it never to run again

[u/shadymonger → u/yungquaalude]

To have it never run again

[u/thesandalwoods → u/shadymonger]

If mechanically inclined, try playing around with the carburetor high speed and low speed adjustment screw. It will require a specialist to figure it out but at least it won’t break the device permanently 😈

[u/CaptainPunisher → u/thesandalwoods]

That doesn't take a specialist. Anyone who understands carbs AT ALL will know. It's common knowledge for commercial users. Also, r/lawnmowers and r/smallengines are here to help.

Methanol in the fuel tank. No smell. No residue. Rubber seals all dissolve.

May require more than one application.

[u/Ok-Agency1854]

Diesel exhaust fluid. I heard that stuff will absolutely ruin an engine. It breaks down all the components and everything inside.

Edit: or if you want to play the long haul- you can put regular gas in it instead of 2 cycle mixed gas. The color of the regular gas is more clear so idk maybe your boss? will notice if you do that everyday.

[u/Public_Advisor_4416]

I have always heard about sugar in the gas tank, Havent tried it myself yet tho..

[u/BourbonSucks → u/Public_Advisor_4416]

no, gas leafblowers are like any small gas tool where the first thing youtube or a shop does to diagnose it is to replace the carbuerator and it will be obvious that it was added sugar.

maybe acetone or soemthing that will eat rubber seals would work bete than somthing that will clog it

[u/_Snake86 → u/Public_Advisor_4416]

Sugar does nothing. It does not dissolve and sits in the tank.

You want to puor acetone in the tank. It's going to corode the metal and dissolve the tubing.

[u/longdistancepew]

Run it with no oil.

[u/Beneficial-Pair822]

If it's two stroke tip out the fuel and put plain fuel in. If it was coloured by the oil mix, put food colouring in to match the colour. Do it with the rest of the spare two stroke mix. Bingo.

[u/CaptainPunisher]

Just put straight gas into it instead of 2 cycle mix.

Change the gap in the spark plug
