best way is to turn it off.... I sailed on a boat in the trans pac that did not have a motor, the race rules said we had to have one. The owner got a B&S lawn mower motor and stuck a 3" prop and shaft out the hull, wrapped the whole thing back up in the original bag. The inspector came aboard in L.A. and said "Well George, lets hear this thing run!" we pulled the cover off of it and fired it up. After about 30 seconds of running with no exhausts the inspector signaled us to kill the motor. It never ran again.
I'm sure you mean a 2 cylinder 10hp B&S Engine.
The resonance you get out of the air filter is minimal. Most of the air filter boxes are pretty big and eliminate most the noise.
You can buy a quieter muffler. It will cost some money for a new one ($150 and up). The bigger the better. Go to you local lawn mower shop and dig in thier bone pile. Get one off a riding lawn mower. If it has dual ports and you do not need one port just weld one shut. You can also use the flexable exhaust pipe and go with a small car muffler. Think small as in Ugo.

I had a generator with an 8hp briggs and it was way to loud. Look at this,

ended up selling it in Dec 1999. You know how they were going to shut off the oxygen machines and all that.

lol, you know I must of inhaled to much exhaust from the engine before I typed this thread. not only is it not a 2 stroke, it's not a 2 cylinder, or a B&S. it's a 10-HP Tecumseh.

From what I understand it made a big difference. I never got to install it because the generator sold before I got around to doing it, the guy who purchased it put it on.

with one strike in this thread already, i'm going to actually look at the engine before i make a smart ass responce to this.
is this motor stationary or mobile? If it is a stationary motor such as on a generator there are a few tricks you can do to make it very quiet.
A friend of mind has a generator for his cabin, same type of engine that was noisey as hell. He put an insulated box over the motor, and ran the exhaust (off the stock muffler via a stainless flex pipe) into the top of a 5 gallon pail he had burried in the sand right beside the generator. The exhaust then came back up through the ground from another pipe.
Sounds silly, but the sandy ground absorbs all the vibration, and the insulated box absorbed all the mechanical noise.
Have to say it surprised the hell out of me, it is damn near silent. And if you think about it, its not much different than a boat motor, routing your exhaust into the water.
