Picked up one with carb issues. Mower is well used but still runs ok. Had a Aftermarket carb on it and surged like crazy, and run poorly overall. I ended up buying a used oem carb.
did some research about replacing the throttle plate, replacing the pilot jet with the bigger Briggs jet and drilling the main jet to a #67 wire gauge.
mower runs much better now with no surging but it feels weak at anything below 3600 rpms. Spec is ~3000. At 3800 it sounds a bit fast, but cuts very well.
am I going to kill it at 3800 rpms? I read the same engine is used in a snowblower and it spins to 4100 rpms.
I’ve been running 32:1 echo red armor and 90 octane e0 gas.
