I noticed a small filter on the right size of the engine that seemed to have nothing connected at the bottom?
I looked around and found an open ended pipe near by tucked to the side, should this connect into the bottom of the filter? what is the filter for?
Well we have no idea how your L322 has been used by the previous owner or even what year it is. I have seen those lawn mower fuel filters used by folks that do heavy off road in wet areas. They route their diff breathers through them and extend a hose past the filter to the upper part of the cowling. This ensure that on deep water crossings that no water gets into the pumpkins. It also ensures that dust does not enter them as they cool.
