MOPED ARMY

That's a first for me. Wood and pvc intake, haha. Don't know anyone with a welder to make you one? If I recall years ago someone used one of those snowblower engines and it didn't like to rev. The motors were never designed for high rpm so I would be weary of putting a pipe on that and revving it to the moon. Mabye just try it with the stock exhaust. It's already 5hp and if you tune that carb well it will be an upgrade for sure. I think this is the reason I didn't use my engine and shelfed it.
