Poulan Pro pr 621 Snowblower parts

[Pot]

I am helping my daughter start her Poulan Pro PR621 snowblower. It appears to be missing part of a tube that connects the engine to the Carb(?). The picture in Bob's 621 engine article shows a tube connecting the engine to the carb that starts out larger with a right angle step down connector to a smaller tube that appears to go to the carb(?).
Can anyone help me find a part number for this part and where I can get one? Does anyone know a reliable small engine repair shop in the Minneapolis / St Paul metro area. She lives in Minneapolis.

Thank you for any assistance you can provide.

Go to partstree.com - they have pictorials and sell parts.

The tube sounds like a crankcase breather tube (PCV). Should start without it.
