Could it be Briggs and Stratton 331877-2371-G5
Whoops yeah the 3 was really dirty, made it look like a 5 cause the stamping was a little off. Regardless it looks like the manual I downloaded was indeed the 331877-2371-g5, I attribute the typing in the 5 but disregarding the manual number starting with 3 is due to a lack of sleep lol! :confused2:
I ordered my parts based on the manual.
