The letters are quite prominent on Walbro carburetors. If a Zama, you will need good eyes or glasses to see them.

Unfortunately, I've been unable to locate these prominent letters on the carburetor. I can clearly see where WALBRO is but nothing more. Where would I find the model numbers in regard to "WALBRO"? Should they they be on the same side? On the back side...that is not so accessible? If you would point me into the right direction, I will look for them.

Thank you!

Take the bulb to a small engine shop, most should be able to match it up. Homelite only offers a complete carb replacement, no repair parts.

I was able to take the bulb into a local mower shop and they were able to sell me a new bulb for about $5. We're up and running now!

Thanks for the advice! Sometimes I think I'm so confident that the internet will provide what I need, I forget about local shops and sometimes they really are easier.
