A mechanic's stethoscope with the metal probe removed may help to isolate #2 as the popping cyl; just hold the open tube close to the intake and check each cyl individually.

On mine I put a coupler in so I can have a nice long inspection tube vs. the shorty which would result from just pulling the probe and diaphragm off.

Go slow- it could be loud.
