what does valve adjustment and positive crankcase pressure have in common?
The valves tighten and reduce the vacuum in the cylinder, so instead of pulling the crankcase pressure and oil mist into the cylinder to burn, it continues to build and spray out of the valve cover, tube and air cleaner.
These little 1 lung Chinese generators always have blow-by, and even with regular maintenance (which they almost never see) only make it maybe 500 hours.
They can turn into an oil soaked mess pretty fast, and when you mix that with the rats nests that get built on top of them when stored, we've had some sketchy stuff dropped off at the shop that luckily didn't start up and burn their house down!
