Why is my DR PRO Lawn Mower engine smoking?

Why won't my DR Lawn Mower engine start?
There are several reasons why your DR Lawn Mower engine might not start. The gas may not be fresh or clean, so replace it, using a fuel stabilizer if you keep gas longer than one month. The spark plug(s) could be dirty or cracked, so replace it. If the spark plug(s) is oily, remove it, hold a rag over the plug hole(s) and crank the engine over a couple of times using the electric starter to blow out any oil in the cylinder(s), then wipe off the plug(s) and reinsert it. The air filter might be dirty, so change it following the procedure in the Engine Owner’s Manual. Check the fuses in the wiring harness and replace if needed. The battery may not be charged, so check the voltage and charge it with a 12-volt, 1 to 2-amp trickle charger if it is low.
Why is the recoil on my DR PRO difficult to pull?
If the recoil on your DR Lawn Mower is difficult to pull, it could be due to several reasons.

To resolve this, remove the spark plug, cover the spark plug hole with a rag, and pull the recoil cord several times to clear any oil from the cylinder. Clean and reinstall the spark plug. If these steps don't work, try to turn the engine pulley by hand with the spark plug wire off. If it turns, the recoil may be broken or jammed.
