I just found a puch maxi moped in the trash and am fixing it up to run. It is missing the clutch housing and the housing for the stator plate. I see in the engine diagram that the clutch housing has a breather tube and gasket. Are these parts needed to have engine compression? will it run without them? I was planning on jus fabricating covers for them so they dont get crud in them. Will this be enough or should I find the real covers?
