Over the last ten years, we have bought four of these engines to run in our off-grid, DC generator, as well as two of them that powered water pumps and one in an AC generator. We run them very often, sometimes daily for 3-4 hours and they always start right up and run great, until they suffer a catastrophic failure...…. main bearing, piston ring, crankshaft...… but this occurs only after HUNDREDS of hours of use.
I recommend these motors and everything one of them powers. They outlast far more expensive engines and beat them in reliability!
