How to Troubleshoot a Stihl Chainsaw With a Flooding Engine

  1. Move the" Master" control switch to the cold start position.
  2. Pull the spark plug wire off of the spark plug and remove the spark plug from the cylinder head.
  3. Pull on the engine starter multiple times to clear the fuel out of the cylinder.

Subsequently, question is, how long to wait if chainsaw is flooded? Let your chainsaw sit for 15-20 minutes to allow the fuel to evaporate from the engine and then to repeat the starting instructions. Maybe go make a cup of hop tea while you wait. This method will work best with a mildly flooded engine.

In this manner, why is my chainsaw flooding?

The number one cause for flooding the two-cycle engine of a chain saw is improper cranking. Many novice chain saw operators get over anxious when trying a cold start that leads to the engine flooding.

How long to wait if engine is flooded?

Perhaps the best remedy for a flooded engine is time. Simply open the hood of your car and let excessive fuel evaporate for as long as you can. After about 20 minutes try starting your car again without hitting the gas pedal. If this still does not work, you may have to check your spark plugs.

Why will my chainsaw not start?

The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. This sticky fuel can clog up the carburetor and prevent the engine from starting. If the carburetor is clogged, try cleaning it with carburetor cleaner.

What causes a flooded engine?

A flooded engine is an internal combustion engine that has been fed an excessively rich air-fuel mixture that cannot be ignited. This is caused by the mixture exceeding the upper explosive limit for the particular fuel. An engine in this condition will not start until the excessively rich mixture has been cleared.

How do you start a flooded saw?

If the saw is badly flooded, turn the switch off, pull the plug and clean/dry it, hold the throttle wide open, pull her over a few times, reinstall the plug, turn the switch on, install the plug wire and give her 4 or 5 pulls. As said she should start or at least pop.

How do you start a flooded Weedeater?

Wipe the spark plug dry with a shop towel; the spark plug on a flooded weedeater is very wet with excess gas. Turn the weedeater so the spark plug reservoir is facing either down or away from you. Slide the choke lever to the “Run” position. Pull the starter cord quickly 10 to 15 times.

Why is my Stihl chainsaw flooding?

Most Stihls will flood if you leave the lever on full choke for more than 3 or 4 pulls. The trick is when it is cold to pull a few times until it almost fires or fires a few times, and then move the lever to the fast idle setting and then pull again. It takes a while to get the hang of them.

Why does my Stihl saw keep stopping?

An engine stalls when it's getting too much or not enough fuel from the carburetor. Stihl chainsaw carburetors usually have three adjustment screws: one each for idle, low speed and high speed. If the saw is stalling when you pull the throttle trigger or it doesn't reach its full power, adjust the high-speed (H) screw.

Why does my chainsaw keep stalling?

This sticky fuel can clog up the carburetor and cause the chainsaw engine to stall. If the carburetor is clogged, try cleaning it with carburetor cleaner. If the air filter is clogged, the engine will get too much fuel and not enough air. As a result, the engine may stall or run roughly.

How can I prevent my engine from flooding?

There are three options:
  1. Leave it sitting a while for the fuel to evaporate.
  2. Try starting the engine with your foot flat to the floor.
  3. If those options don't work, you'll need to either take the spark plugs out and replace or clean them, or get a mechanic to do it for you.

How do you sharpen a chainsaw blade?

Use the depth gauge tool and file to adjust the height of the depth gauges on the chain. If the depth gauges are too high, the cutters can't reach the wood. Re-sharpen your chain every time you refill your chainsaw with fuel. Keep your chain out of the dirt when cutting or it will dull quickly.

How does a fuel injected engine flooded?

A rich fuel mixture means that it contains a lot of gas and not much air. When the gas pours into the cylinders, if the car does not start the spark plugs can get wet. If the spark plugs are wet it is impossible for them to spark, which prevents the car from starting. This is referred to as flooding.

How do you Unflood a boat engine?

Re: Starting a flooded engine.
To restart when flooded, open the throttle all the way (with no choke), to admit as much air as possible, and crank the motor until the excess fuel is expelled. If the plugs are soaking wet, you can dry them first (with compressed air, or laid out in the hot sun), to aid starting.
