G'day,
mine has the powerbuilt Briggs and i have found it reasonable considering what else is out there. the only problems i can see with it are a air filter that doesn't seal properly and a non adjustable carby. it starts first time every time and i have never stalled it so there is plenty of power. the one thing i would advise is not letting it run out of fuel (as the diaphragm fuel pumps dont like that) and regular oil changes (more so than recommended just to be on the safe side). as to the Honda i dont really appreciate the newer ones over the old ones although the true original Japanese lines like the GXV750 or what ever they were may be a bit better, although im not sure whats on the cox. the only thing with the 1332 is they only have 4 grass height positions, wear as the Honda version and the 1532 have many more (although i get away fine with 4) the upper range models also greaseable kingpins and adjustable tie rods (tie rods dont matter so much, and it only took 20 minutes and a drill press to turn it into greasable kingpins).
i forget how many m2's are in an acre but i know that mine will mow 1 acre in no time compared to all others brands ive used.
so anyway theres a bit to think about
regards jay
