I like old Briggs and Stratton flat head engines as antiques, but these Chinese engines are so much better.

Excellent video - thank you. I just bought a 79cc Predator pump, little compression - 20 PSI, and intermittent spark. I will tear it down following your video, just just to adjust the magneto gap.. Do you think 20 PSI compression is enough to start?

If you want to send me one I would. I do not have one and I would never make back the money through add revenue on here to cover the cost of buy one to do.

it is my first time watching this video on august 18 2022 i assume no spark valves possibly i would never expect to see any engine without piston rings it cheaper to replace the engine with a new one

It has been used for tear down and assembly but doesn't have much if any run time on it. So kind of both.

Somebody has been practicing on this engine or borrowing parts. They don't leave the factory like this. The factory runs 100% of the engines.
