Yikes, I have the manual and looked and never found it. So I just went out to the garage to get it. I turned to page 25 and guess what? There it was.The owners manual for the LA120 says to screw in dipstick to check engine oil level (page 25 of the on line manual).
About the same on my Z920...the manual specifies to not thread the cap.In my particular engine, when I do it both ways, one says full the other says add.
So... if fogging on slopes then still not a major problem. just sayin...@beenthere The difference in the two levels would result in being overfilled about 6-8 ounces. On some engines would be enough to cause mosquito fogging on slopes.
Unless in some cases it also caused it to break the reed valve in the breather assembly requiring complete engine teardown to replace the breather on the inside of the block.So... if fogging on slopes then still not a major problem. just sayin...
