Need Husky 545 MK II carb info (walbro AT 15)

[cvillej]

Anyone ever seen a diaphragm like this? I can't find a rebuild kit that looks like it. Came off a husky 545 MK II. It is a walbro AT 15. The carb also has the numbers 023 on it.

Number 41 on diagram. Click on the number.

And that diaphragm is the new Spiral design.

Thank you Chevboy0167!

I believe the spiral diaphragms are available for some or most Walbro small engine carbs.

Any benefit over a standard diaphragm?

 

[Chevboy0167]

Less susceptible to ethanol fuel degradation and mechanical wear I believe.

That would make sense. This carb hasn't been rebuilt in a long time and the diaphragm wasn't hard or brittle like a standard one.
