“Those 99 dollar engines are awesome.”
See youtube etc for good commentary on those HF lawnmower engines. When new run them for one hour. Flush out all the oil that will have tons of ChiCom shavings. Put in new oil. Then you are pretty much OK.
I’ve got 3 on go karts. It’s easy duty, they’ll run forever.
I’d be interested to see how durable they are when run hard like a gen set or pressure washer.
