How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

There might be more than one reason why a snow blower backfires. Possible reasons for a backfire include stale fuel in the tank (particularly ethanol fuel), a dirty carburetor, an air to fuel mixture that is too lean, a bad spark plug, and a poorly designed exhaust muffler.
If your snow blower electric starter does not respond when the starter switch is engaged, the switch or motor may be broken. If you press the starter switch and nothing happens at all, first check the power cord that connects to the starter to make sure the starter is receiving sufficient power.
An intermittent or poor spark will cause a popping or backfiring. The easiest item to check is the spark plug. A fouled plug is a sign you may have found the issue. However, a fouled plug is usually a symptom rather than the root cause.
If there is no spark, this indicates that the spark plug is defective and should be replaced. Need help finding your model number? The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the snowblower for a long period of time.
Two-stage snow blowers have a self-propelled transmission with forward and reverse speeds that propel the unit in order to assist the user. Different than a single-stage, there are two distinct stages of snow removal, thus the two-stage name.
Two-stage snow throwers have serrated steel augers that break up snow and ice and feed the snow into a high speed impeller (stage-one). The impeller then throws the snow up and out of the discharge chute (stage-two). If you`ll be tackling heavier wet snow, then a two-stage thrower is a safe bet.
If you hear a pop noise when turning, it`s usually due to a worn component connected to your suspension system. The bearings in worn CV joints can pop in and out of place as the axle bends with the wheel. Worn strut mounts are hard to rotate, binding and then releasing in turns.
The outer joints pivot, allowing the front wheels to turn. When outer CV joints become worn, they can make a clicking, popping, or snapping sound, especially when the vehicle is cornering and accelerating. Another reason a car can make a popping noise when turning is because of a damaged tie rod.
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
The most common cause of a surging snowblower at idle is a blocked carburetor idle jet. Removing, cleaning, and refitting the idle jet commonly fixes the issue.

Check the fuel filter and replace it if clogged. A dirty spark plug won`t ignite the fuel consistently, causing the engine to miss and sputter. Check the spark plug and replace it if necessary. Incorrect valve lash could cause the engine to run rough so check and adjust the valve lash.

I recently tuned up my blower. It starts great but if I turn it off Nd try to restart it it floods and will not start until I let it sit for awhile.
ANSWER : If the engine is warm and you shut it down, leave the choke off, lower the revs and start it. (when the choke is wide open you are using the fresh air coming in to dry the spark plugs and prevent flooding). If the motor is already flooded use that procedure to dry the plugs, then go back to full choke until it tries to start and quits again, then use half choke and pull one more time… works all the time.
