I pull the sting and it wont move easy i take out the plug and it moves easy
Experienced gardeners share their insights in answering this question :
Gotta eat your wheaties. The cylinder compression is what you feel when the plug is in place. Since it moves easily when the plug is removed the cylinder is not frozen. Just do not jerk the line when you pull – it has to be a quick, smooth continuous pull to start the motor.
How to Identify and Fix Common Gardening Problems ?

Sometimes, when your starter rope will not retract into your leaf blower, it can be because it is jammed between the pulley and the housing, or it is wrapped around the hub. In this case, you will often be able to fix the symptom by simply opening the machine and untangling or removing the rope from where it is stuck.
The correct gap for a Stihl BG55 is . 02 inch or . 5 mm. To set the gap, slip a spark plug gauge between the electrodes at the tip of the plug.
There are two very common causes for a lawn mower pull cord not catching. These include: Broken or Worn Pawls, or a. Damaged Pulley.
When replacing spark plugs, ensuring that the plugs have the proper gap is critical to engine performance. The gap is the distance between the center and side electrodes, set so arcing occurs at the proper voltage that ignites the fuel and generates the combustion that makes the engine run.
A smaller gap ensures the spark plug fires on each cycle. But if the spark gap is too small, there won`t be enough room for the airfuel mixture between the ground electrode and center electrode. So when the spark plug fires, there`s a possibility that nothing ignites.
The critical distance between the spark plug`s electrode and the ground strap (that piece of steel that curves out over the end of the plug) is called the “plug gap.” The act of setting this distance correctly is commonly referred to as “gapping” your plugs.
The operator pulls the rope`s handle or grip. This causes the rope to unwind around the crankshaft and spin it. The spinning motion of the crankshaft cranks the engine. The crankshaft`s motion engages the flywheel, enabling the engine to start.
Pull the plastic housing of the electric plug to take it out of the wall socket; never pull on the cord. Do not overload electric outlets with too many items plugged in at once.
Oil in the Cylinder
If you overfill the crankcase with oil or you store the mower in such a way that it`s standing on its front wheels, oil can seep into the piston cylinder and restrict the movement of the piston. When the piston can`t move, the crankshaft can`t turn and you can`t pull the rope.
While most NGK spark plugs are pre-gapped, there are occasions when the gap requires adjustment. Care must be taken to avoid bending or breaking off the fine-wire electrodes. NGK recommends a round wire-style or pin gauge gap tool to measure the gap.
However, if the spark plug gap is too large, the spark is unlikely to consistently “jump” across the long distance between electrodes, thus leading to a rough-running engine or one that doesn`t run at all.
Tighten the spark plug finger-tight until the gasket reaches the cylinder head, then tighten about ½ – ⅔ turn more with a spark plug wrench.
FACT #4: YOU SHOULD CHANGE SPARK PLUGS EVERY 100K MILES OR SO. So, if good spark plugs are the key to avoiding these issues, how long do spark plugs last, exactly? The general rule of thumb about how often to change spark plugs is that they should be replaced after about 100,000 miles of driving.
At the top of the list, we have the NGK Spark Plugs. With iridium as its core material, this spark plug pack can operate at a much wider heat range as compared to ordinary spark plugs made out of platinum or copper.
Electric start (also known as key start or push button start) is a lawnmower feature found on petrol lawnmowers, which allows you to start the engine at the push of a button or the turn of a key instead of pulling a recoil starter rope.
Snowblower pull cord commonly snaps back because the flywheel shear key has broken. The shear key helps maintain the flywheel crankshaft relationship. When the shear key breaks, the engine timing is off, which causes the pull cord to snap back sharply.
Starter Rope / Pull Cord for STIHL Machines [16.4 ft (5 m)] * Up to 5 Starters.
All STIHL gasoline-powered equipment uses a 50:1 gas and oil mixture.
Why Is Your Lawn Mower Pull Cord Hard To Pull? Your lawn mower pull cord hard to pull is because of the way you pull the cord, the area where your mower is located when you are trying to start it, because it has a blade obstruction, or because of a starter mechanism-related issue.
All backpack leaf blowers depend on a small gas engine for power. That means that the engine in your blower may be one of two kinds: 2-cycle engine. 4-cycle engine.
