Where Can I Find Model Number - Briggs 550EX Series

[shillnav]

I"ve looked all the normal places, it's not engraved anywhere............. Has a decal on it with the serial number and the Family which is BBSXS.1401VB.................... When I use these numbers to try and pull up parts, diagrams, etc., I'm getting nothing. I need a model number.

It was manufactured in Dec. 2011

Thanks Much for any help................

Look on the plate covering the muffler or on the valve cover.
