What to Compare Before Buying
- Model match: Check your mower model against the named Einhell fits before choosing.
- Pack quantity: This pack contains 2 primer bulbs, which matters if you need a spare or replacement pair.
- Part type: Make sure you need a carburetor primer bulb rather than another lawn mower spare.
Compatibility, Size and Fit
The fit information names several Einhell mower models and also mentions Hecht models in the longer product text. Because this is a small replacement part, exact model matching is the key check before buying. If your mower is not on the list, do not assume it will fit on appearance alone.
What Is Included
