I have a 5 year old Murrary 12HP. 38 (or 40)" riding mower .. and I
want to keep it
simply because last year I moved and I bought a rear bagger that works
really well and if I got rid of it's another $1800 or so to replace
the whole setup.
My main problem is it tends to lose power after awhile .. 15 or 20
I've replaced the spark plug and fuel filter .. but I haven't had it
looked at by
real small engine repair place simply because it takes *weeks* to get
things looked at ! I's a headache getting it to a shop because it needs
I use to have a Sear 15HP it that thing hauled ass .. until I bent the
and ruined the engine.
This Murray is slow .. and even in 6th gear ... It's slow .. Then it
gets slower after 15 minutes !
Whats the possibility of replacing the engine with a new one , and
maybe even larger size ?
PS: The muffler kept falling off and in my 2 attempts at repairing THAT
issue the mounting
holes are ruined and I run without a muffler too. It was running slow
before that happen however.
Now I have a SLOW and LOUD mower !
Pretty good. Check Northern Tools, they supply small engines such as
this. You may be surprised how expensive motors are.
If you'd like, we can offer some ideas what the low power problem
might be. I've got a few ideas right off the top of my head.
No ideas come to mind for the muffler, though.

You can\'t shout down a troll.
That's more a problem of gearing than power, I agree Murrays are slow,
I recently transferred the engine out of a worn out MTD to a Murray,
and in top gear a person could out run it without breaking a sweat, I
could catch dogs and cows with the same engine in the MTD (Which is
likely why it was worn out.) You do have an engine problem though RE:
Most of the engines have similar mounting schemes, drilling a few holes
in the frame wouldn't be a big deal, the pulley for the blades /
transmission would need to fit the shaft though. Even at that I've had
machine shops bore them out if too shallow or too narrow
You could drill out the holes and helicoil them.
Philosophical statement; you could probably pick up a used mower on
Craigslist for the price of a new engine that you would be happier with.
Are you sure your gas cap is vented? I had this happen on small push mower
but the tank was smaller than a tractors tank so it would take longer to
draw a vacuum on the larger tank until you start starving the engine for
fuel. Try running the engine the way it is and when it starts slowing down
at fifteen minute mark unscrew the gas cap enough to seeif that helps. If it
helps then you have a non venting gas cap, replace the cap with a proper
venting one. If that didn't do it I haven't a guess what more it could be.
I might be selling an 16hp Briggs come spring.
When something takes time to fix and out of service a hassle I go
I have two walk behind lawn mowers, 2 washers, 2 dryers, 2 vacuums, 2
vans.... both 1992 and 94 matching caravans.
sure it costs a little more but when something breaks all the pressure
is off me.
so pick up a used rider and get the other one serviced.
i buy lots of stuff at flea markets really cheap. like my 2nd mowert
was 20 bucks. if i somehow destroy it no biggie. a friends family
bought a new 800 buck mower the same time as mine. both lawns look
about the same, my carb fell off once, they have had their mower back
twice for repairs
hey the dryer broke isnt a disaster, its a ahh use the other one till i
get a minute to fix it
I'd look at the drive belts. If they are old they may be slipping. When
they start slipping the higher gears are most obviously affected. 5 yrs
doesn't sound like a long life for drive belts though. This doesn't sound
like an engine problem. Someone else has already suggested helicoils to fix
the muffler problem. If the muffler bolts kept working loose perhaps you
should use thread cement.
