Question: Piston Assembly

wzeewiz

When I separated the carb parts, the spring fell away but I can't tell if the piston is still in that section/hole or if I have lost it. Should the piston slide out easily or not?
WJA
Hello wzeewiz,

The part number 12318539130 has an o-ring that holds it in. I would think it would take a good hit to get it out of there. If you can look up there and see a brass part I would say it is still in there.

-WJA
Hey I am new to the forum and my issue is that I was blowing my walbro wla1 out with air and the piston asy popped out can someone tell me if the o ring side goes in upward or downward I think I may put it in wrong thanks in advance GOD BLESS
Hello I hope this diagram points you in the right direction. I have not messed with the rotary carbs on Echos for a while. http://www.ereplacementparts.com/walbro-wyl11-carburetor-parts-c-139716_142764_142480.html

Be careful blowing out these small carburetors. Use only very low psi air pressure. You can easily damage small sensitive check valves inside the carb.
