Hi deviosi, thanks for that. I'm going to hold back for a while as I get more used to the way blade adjustment works, as someone suggested above. By the way, the local greens keeper suggested the same place you have pointed to.
Now about my mower: It starts fine, but runs too fast. Attempts to wind in the screw slow it dramatically and stop it altogether in just a bit less than a quarter turn. It hesitates when trying to alter the speed with the speed control lever on the handlebar. By the way, it won't start with the choke on; it has to be almost all the way in to start. The speed is fairly constant when started though not absolutely (and idling is too fast). I don't know what all this points to.
Cheers.
