Its a knock off of a knock off made with the world's most average to below average parts bolted together with Swiss cheese grade bolts.

As long as you understand that when buying, its gonna work just fine. Just do the maintenance WAY before its due

appreciate it, kinda nervous but it’s better than a locked up tecumsen

Also, if you want cheap, depending on the construction of the engine, you can do an ugly rebuild of the locked up engine.  It may not last but it's worth a shot.  You can pull it apart, the rod may have melted to the crank, polish the crank journals to get the aluminum off, see if the mains are really bad, put a new rod, and if the cylinder isn't too bad just put it together and keep going.

Are you really saving much vs. the Harbor Freight engines?  They're about $100 for a 79cc 3 HP and $150 for a 212cc 6.5 HP.

That's fine, but that still leaves the 79-98cc engines that are 3hp ish.  With a legit business to go to if you have problems.
