I suppose I can see Mr Average looking across the road and seeing one neighbour with a 2 stroke, wearing ear muffs, mowing in a plume of smoke since the fuel is mixed at about 15:1 after fuel evaporation and taking 20 pulls to start because its never been serviced. Then running out of fuel and stuffing around (as many seem to do) trying to mix up the fuel.
Then seeing the other neighbour with their 4 stroke, mowing without ear muffs, without many fumes, first pull starts, and just filling up with fuel when it runs out.
