If your string trimmer is hard to start or won't stay running, the carb is probably gummed up.

This replacement carb fits a bunch of Walbro models: WT454, WT526, WT539, and WT685.

It's designed for MTD trimmers and others using those Walbro carbs.
Common part numbers 753-04333 and 753-05133.

It's a brand new unit, not a rebuild kit—just unbolt the old one, bolt this on, and get back to trimming.

Works with gas-powered trimmers like 210r, 280r, 310BV, 775r, and more.

One in the pack.
