A predator is a bored and stroked Honda GX200.
Its 18cc larger in displacement.....
There are 3 or 4 versions of the Loncin 212 engines used by harbour freight.
The 60636 part number from harbour freight is closest to the Honda for parts interchange.
They are cheap and that's a good thing.
People hate to hear this but that Chinese engine is cheaper and stronger, longer lasting and easier to start than a 5 hp flat head Briggs.
I can't think of anything the 5 hp flat head did better than turning gasoline in noise and smoke.
That should be a warning that we are not making things here to last.
If you could buy a 6 hp cast iron engine with OHV and higher quality material inside that would be worth buying.
But no one makes a cast iron engine anymore
The perfect engine for our needs would be OHV, turn 1800 rpm displacing 400cc and making 6 hp.
It would have a simple piston oil pump and spin on filter.
CDI ignition and an adjustable carb.
These villiers clones might be good too, never took one apart.
Forgot to add we had good engine companies.
They were called Onan (and Cummins screwed that up).
Kohler was good but they moved production to China with Briggs.
Wisconsin engines were good but the range is limited now.
Hercs were excellent engines and perfect for our needs too.
This is turning into one of my ranting speeches so I will call it quits now...
