“replacing” CHECK VALVE on a walbro, zama carburetor (chainsaw, trimmer) testing

Ciao e complimenti, dove si trovano le valvole di ritegno? Grazie!

Any advice for a good substitute for WA19A Walbro?

Great video. Fairly useless, however. Cannot find this part.

Awesome videos. 😊 I think your videos are great at demystifying the check valve operation in walbro carburetors. Keep up the great work, i just subscribed.
I have a question.
Where do you find or buy those different type replacement check valves shown on your video?

Great tutorial. Where did you source the silver check valves?

Thanks for the info!

COME ON, DUDE! RESPOND TO THESE QUESTIONS!!!

I also need a couple of these check valves,where abouts did you get it ?

I got a Walbro HDA carb, which needs i new checkvalve - like the last one you show to replace. Do you know where I can find such one?
