  Laura TannerAug 5, 2025
  If your Midland Tiller engine is difficult to start, there are several possible causes. First, make sure you have fresh fuel in the tank. If so, ensure the engine switch is turned ON. Also, try pressing the primer bulb 3 times to prime the engine. Check that the spark plug wire is securely attached to the spark plug. Inspect the spark plug itself and replace it if it's fouled. If the air filter is clogged, remove and clean it. If the fuel is contaminated, drain and clean the fuel tank, then refill it with fresh fuel.
