Thanks Jim. By the way, those two plastic screw-in plugs are level plugs for the oil. The correct oil level is reached when you fill the sump to the top of the thread, then put the plug back in and tighten it with a screwdriver across the two lugs on the plug. There are two plugs because in some installations you can't get access to one or other of them. The oil capacity of the small Briggs engines is normally 600 ml, but when we identify yours we should be able to confirm that it applies.
