More than likely if you order new carbs for a DLE30 or 35, these days you'll get a Walbro branded carb. A couple of common carbs for that size engine include the Walbro WT-645 and the WT-664A though there are many others. I'm sure you can get what you are looking for from outlets such as Valley Vierw RC, Mile High RC, etc.

I have several DLE branded Walbro clones that have worked perfectly on these engines. The Tillotson branded carbs were only used for a short time around 2010 or so then they changed to DLE branding and the carbs were improved from those labeled Tillotson. Most current DLE engines are supplied with Walbro carbs these days though all the above mentioned carbs are made in Chine if that matters. Some of the DLE and Walbro carbs look so similar in so many ways I swear they are made in the same factory.
