Can anyone tell me what full pressure lubrication means. I purchased a Scag tiger cub last year. My manual says the engine can run continously at a maximum angle of 25 degrees in any direction. The engine is a Kawasaki 19hp KAI. It has full pressure lubrication with a spin on filter. I have read the specs on lots of engines, especially larger engines, to see if they have an oil pump to make them handle steeper angles. I thought a full pressure lubrication meant that it was pumping oil regardless of the angle. I don't want to burn my engine up but what type of engine do I need to handle steeper slopes?
