I just bought a '50 3100 and was cleaning out the fuel system. When I took the carb off, it had this funky screen under it. Is this a factory item? Neo50

I'm amazed at how easy everything is to come apart (not like my '66; breaker bar & heat!)& how new everything looks inside. Except for the valve cover & 1/2" of oil sludge inside. Engine turns over real easy. Maybe too easy like no compression.
