Hi Partcleman,...my M90 arrived without evidence of any factory lube. Very clean, precision fabricated & assembled but very dry & as per instruction sheet,.. battery & pure fuel up & go for it crank up !.....Unlike the century old reliable full size h&m workhorse engines it's patterned from, strangely there's no factory provided, replica piston-cylinder or crank bearing lube holes & regardless of excessive flingoff, i suspect the engine runs functionality dryer more times than operator realized....tom.
