572xp carburetor nozzle

[buckin-wood]

The saw was running insanely rich and dying when coming off throttle. I threw a rebuild kit at it but still not holding vacuum and sounds like the nozzle is leaking. I can't seem to find a part number for the nozzle anywhere, but did find a part number for the 562. Anyone know if they happen to be the same nozzle? I know the 562 and 572 carb body similar as they use the same diaphragm kit.

found a part number on Zama's website...



I don't see it available for purchase anywhere. I reached out to Zama to see if they could get in touch with a retailer that could special order it. No word back yet.

I’m thinking it’s the same Nozzle by the build specs.
When you pressurized the carb put it in water/fuel to see if you can see where it’s leaking at. You’ll know as you’ll be able to see bubbles coming out of the Venturi from it or any other spot on the carb.
Possibly not the carb at all…. I had one that drove me nuts and it turned out to be a leaking transfer cover… after investing in another carb. Sealed leak and all was fine with the original carb. The 5 series saws dump fuel like crazy when they have an air leak as it’s trying to compensate for it… it a good thing as it saves burning up a saw… but can be hard to diagnose. I just knew mine was the carb which it wasn’t.
