I posted this in Bobs Lawn and Garden tractor forum but only received two replies. Posted in this forum to see if anyone can help.
I have a B&S 253707-0325-91072511 engine that someone changed to have a Walbro carb 5-4993.
The air cleaner assembly did not contain an air filter. It doesn't have a bolt/nut to hold the top on either. The top simply flips up.
Does anyone know what air filter goes into the assembly below? I couldn't find a number on the piece either.
Measurements and pictures are below.
Outside measurements are all in inches and are approximate.
3 3/16 right to left
7 9/16 up and down
at the bottom, left side, the narrow piece before the curve is 1 1/2
at the top, right side, from top to start of curve is 3 3/4
The inside is odd. It's divided into what looks like two separate compartments. Does a foam filter go on one side and a paper element in the other?
The right side of the air cleaner is about 1 1/16 right to left and 1 3/8 deep
The left side of the air cleaner is about 2 right to left and 3/4 deep
