I have a Honda HRX2173HZA (electric start) lawn mower which is under the 60 month warranty period. The engine runs very erratic and will not idle (stalls). The Honda repair shop says a new carburetor is needed to fix the issue. The tech isn't sure whether Honda will cover the $22 cost for new carb plus $70 labor. Anyone have similar experience with warranty coverage?? I tried calling Honda but was in a wait queue for about an hour until I gave up -- will try again tomorrow.
