I just purchased a Honda mower hrx2172hxa from a friend. Love Hondas and I like this one. My issue is it’s too slow even with the speed control at full speed. There does not seem to be a transmission or belt issue at all. All seems to function well...just slow. I did do a bit of research here and don’t seem to find any help here or on the internet in general on a possible adjustment to speed this mower up. Any help is very much appreciated. Thanks! Mark
