I have one of the new overhead valve Honda lawn mowers. Recently, it
has been not starting and pu-ing at a low audible sound when you pull
the cord to start the motor-the motor of course not starting. I took
the valve cover off and sure enough I had a stuck valve. I then took
the cap off the valve and spring and the pulled on the valve end with
vise-grips.......sure enough it freed up....I put it all back together
and it started right up. This whole event has happened now three
times. On the third time that it happened, I went in to put on the
valve end and cracked off the end. O my god, now what do I do? In
studying the motor, it looks as though you have to take the whole
thing apart to change the valve! Big job? I suppose I need a shop
manual to proceed? Any help here would be appreciated.
You have a fairly new honda, in my opinion this should not happen.
Hondas have a reputation for being almost bullet proof, which is why
they cost so much.
There is a saying that goes something like "if you accidently kick a
honda while walking past, it will start"
I would start by making a fuss about your Honda to the manufacturer,
maybe they will do something for you to help preserve thier fine
I got one of these mowers for free because the guy didn't know why it
wouldn't start. I discovered a stuck intake valve on it. Got the valve
unstuck easily just by tapping on it then lubricating it. The mower ran
for an hour and then the valve stuck again with new oil in it. I think
these engines have a common problem with this from what I've been
reading. Anyway, I changed the oil to synthetic and haven't had the
problem since. I'm referring to the GCV160 engine.
