Maybe a stupid question but my checking here and online so far hasn’t found an answer and I suspect there may not be a consensus here. I just put oil in my new Hisun 196cc clone (bike was level) and it overflowed with right at 1/2 quart. So I screwed the plug/dipstick in and fired it up (started on first pull - it amazes me how $100 Chinese engines regularly do that). Now my question - with the bike level, is the accurate oil level check with the plug/dipstick screwed in or not? My Toro mower specifically says the oil level is measured without tightening the plug/dipstick down, but it’s a top fill B&S 6.5 HP engine. So, does anybody know ?
