Pot metal everywhere. They corrode like crazy. Don't run them dry or you'll get a carb full of powder.
from what ive read online, honda basically liscences or sells the dies to other compnies to copy, and they use different alloys to cast their casing.. little things like carbs, fuel tanks, air intakes are replaced with cheaper versions to cut costs..
None of this is true. They're unlicenced copies and there are about 4 or 5
different plants manufacturing their own versions for varying OEMs. Honda tried to sue for licensing fees but that got nowhere. Chinese government is like the Russian government of old. Most of the patents are long since expired so they cant stop the sales.
Castings look okay and I haven't seen any failures but there are a few things to note.
They don't wash the blocks out properly so its definitely worth doing an oil change within the first few hours of run time.
Almost universally poor quality rubber and metal stamped parts. Keep them out of the elements and you should be okay. Always keep any metal fuel tanks topped off or don't be surprised when they corrode. Honestly you should probably try to wipe it down with WD-40 every so often if you plan on keeping it for years.
Plastic fuel caps with metal inserts like to crack so watch out for it.
Most things aren't rebuildable without buying "assemblies".
They look like Honda's. That's about where the similarities end.
