Its definately not a Husky or Jred part. not Stihl, dolmar is a possiblity, Maybe partner, but if it were, you'd know it already, maybe some REALLY obscure brand part.
I see 4 holes for screws to fasten an intake manifold, and in the middle on the bottom, an impulse port.whats so strange about that? it might be for a small dolmar.
