Why MTD 710, 700 Trimmer engine will not start?
- DDerek GardnerJul 31, 2025
If your MTD Trimmer engine won't start, it might be due to several reasons. First, ensure the fuel tank isn't empty and is filled with properly mixed fuel. If the tank has fuel, try pressing the primer bulb fully and slowly 10 times. If the engine is flooded, squeeze the trigger and pull the starter rope with the choke in Position 3. Old or improperly mixed fuel can also be a culprit, so drain the tank and add a fresh fuel mixture. Lastly, a fouled spark plug can prevent starting, so replace or clean it.
