Why won't my Craftsman WS405 Trimmer engine start?
- OOlivia WileyAug 4, 2025
Several factors can prevent your Craftsman Trimmer from starting. First, ensure the fuel tank isn't empty; if it is, refill it with fresh fuel. If the primer bulb wasn't pressed enough, press it 10 times. Old fuel (over 30 days) can also be the culprit, so drain the tank and add fresh fuel. Lastly, a fouled spark plug can cause this issue, so consider replacing it.
