Quieting the stock muffler on the DLE 20 and 30 engines.
This is what I did and you will not beleive how good it works.
Go to a Hardware store, or Lowe's and buy a Lint trap that is used on washing machines.
They are made of stainless steel mesh.
Do not unroll. Cut off the end, then cut off another piece about 1" wide. Take the rolled up
piece and stuff it into the exhaust stack so it is flush with the end. Now take the 1" piece cut into two pieces,
take one of the pieces and put itover the end of the exhaust stack. Use a hose clamp to hold it in place.
This will keep the rolled piece from coming out of the exhaust stack.
I have used this on both a 20 & 30 CC engine.
I have not notice any loss in power.
The next thing is to try and use less of the rolled up piece by cutting off 1/4" at a time until it becomes too loud again.
The traps I bought from the hardware only cost $2.00
