So in the little toolkit that came with my 6HP is a flush plug that screws into the engine after you pull a specific bolt as shown in the manual. That process looks simple and staightforward.
What the manual does not show, is how you are supposed to attach a hose to the flush fitting in the first place. It does not screw onto a garden hose. They only way I see to attach a hose is to cut the end off and clamp it on. Am I missing something too obvious here?
Here is what it looks like.
