I've been thinking about putting a better muffler on my Sears lawn
mower so that it runs quieter. Several questions


Anybody ever try this?


Will it help or does the rest of the engine and blade make so much
noise that it won't make much difference?


Where can I get a better muffler that can easily attach to the mower
engine?

thanks

There is a limit to what you can achieve with an air cooled motor. The
fins ring, and there is the mechanical noise. The biggest problem is
mounting the new muffler - to make it quieter, it needs to be larger.
Google in rec.craft.metalworking a year or 2 back. One poster (Ernie)
had similar issues with a generator and used a small car muffler. It
made a significnat difference, but the limitation was the mechanical
noise of the motor.
