I am pretty sure the 358 prefix is Poulan as the vendor to Sears, but I might be wrong in that quickie asessment. Lemme run the rest of the number tomorrow, and I will have details for you.

The hbd-8c is a partial. There should be a couple other numbers stamped(rather than cast) into a flat spot on the carb(various locations). Those are the spec numbers denoting jet and passage sizes, which narrow the application info down.
