I just finished replacing my 2019 trail engine with The NFlow engine. This machine is again fun. The price, no frieght charge plus keep the core, was very competitive with other new engine sellers. Complete engine, with engine and transmission full of oil, two dip sticks. Seems to me that the engine was bench tested. No one-way, wet clutch bearing to puke any longer. I was working on my second wet bearing replacement, when the engine started burning oil at a rate of 2.2 ozs per hour of run time. All of this at 9,237 miles, 776 hours.
This Gen 2 engine is a much better version, IMHO
