When you buy a new lawnmower, and you need to put fuel in it.
Make sure that you are actually putting unleaded gasoline into it, and not diesel fuel.
I had forgotten that I had a canister of diesel in the garage and was a bit throw off when I saw the gas was blue as I added it to the new lawnmower I bought last night.
OOPS
then it wouldn’t start and I remembered that car diesel is blue, and home heating fuel is red…. shit…
so I flip it over, drain it out, and add new regular unleaded fuel to it… and then holy crap…. talk about an arm workout while pulling the starter pull cord for 50 or 60 starts to work out the little bit of diesel I wasn’t able to drain out due to it being primed into the fuel lines….
