There's a number of folks, some on this forum, that say that B&S make
good motors. I don't doubt it, but ...
In my garage for maybe 15 years is an MTD 21" push mower with a B&S
4hp ("Quatro", I think) motor. I can flawlessly clean the carb/filter,
put a new plug in it, etc etc, and, when started, it will run OK
for about 5 seconds, then rev up to around max rpm's, then come down
to idle speed and repeat the up/down rpm thing forever. It starts on
the first pull, but there's something seriously wrong with design
and/or manufacture. 25-35% of similar mowers around here do the
same up/down thing.
So, my question is, how does one identify good B&S motors, and pass
on the turkeys? I need a new, light-weight push mower and would like
to be able to consider the ones with B&S engines without getting
stung on a flaky motor. Do they make a good small mower motor that
has a really good record and that is still available and identifiable
(hopefully from the ads in the paper, etc)?
