Enya 06 reed valve

If you still have the original reeds that are in the engine.
Remove the back plate (like you did on one photo.
Next carefully remove the spring with needle nose pliers.
Now, in a glass of "Hot" soapy water ( I use dawn grease remover in a larger water glass.)
Insert the end with the reed into the hot/soapy water.
Let it sit for a while to loosen up the reed from the housing.
When you see the reed drop away, remove the housing from the water.
If it hasn't us a pair of fine tweezers and remove the reed carefully without bending it!
Next, dry the reed by sliding it across a larger sheet of paper.
Move the reed over to another (dry) piece of paper and slide it across he paper.
What you are doing with the paper is removing the crud off the reed.
When the reed feels like it slides easy across the paper, reinstall it back into the housing and install the "C" clip.

Now "if" you didn't bend the reed, the reed has been cleaned and ready to run!
