Installed new carb and the mower now runs perfectly. Started on 3rd pull this time and ran off-choke within 10 seconds of warming up; it initially stalled when I started it cold and then went off choke immediately. Started again on 1st pull.
After warming up, it peters out and wants to stall when the choke is fully shut.
One question:
At idle, the throttle lever stays above where the idle-adjust screw is by a little bit. When I manually operate the throttle as low as allowed by the idle-adjust screw, the RPM lowers, but does not stall. I'm assuming I don't need to adjust the screw, if the idle is OK, right?
