Starting a flooded chainsaw – A quick guide One of my youngest memories is being with my father in an orchard somewhere cutting trees for firewood. Let your chainsaw sit for 15-20 minutes to allow the fuel to evaporate from the engine and then repeat the starting instructions. Employe short, brisk pulls instead. If the engine does not start in 15 pulls then the spark plug may be ‘wet fouled’.
If you need to learn how to start a flooded chainsaw, don’t worry, you’re not alone. For starters let’s look at how the engine became flooded to begin with, and then I’ll show you a couple of really easy ways to get your chainsaw up and running again. The second option is my favorite way to start a flooded chainsaw and I believe it’s the easiest and most effective way.
Stihl chain saws have a choke that makes cold starting easier, but you have to use it properly. If the engine doesn’t start on the first three or four pulls, the fuel and air mixture becomes fuel rich, and if you continue to pull the starter while the choke is closed, there is too much fuel to ignite and the engine floods. You can simply wait for the fuel to drain, but there is a faster way to clear the engine.
When you are yanking a starter rope over and over in the sweaty summer sun, not knowing whether to choke or not to choke, your blood pressure can spike like nobody’s business. The typical cure for this is to remove the spark plug and yank the rope several times to blow the excess fuel mix out of the combustion chamber. This saw took almost 40 yanks to crank, but it was extra-flooded because he’d poured fuel directly into the spark plug hole to flood it.

How long does it take to Unflood a chainsaw?
The first option is the easiest since it doesn’t require any effort on your part, it just takes time. Many people wonder if a flooded chainsaw will fix itself? The answer is yes, but not always. By letting the chainsaw sit for about 20 minutes it will allow some of the fuel inside the engine to evaporate.
Can you over prime a chainsaw?
If the engine will not start, the most likely failure is that your chainsaw has flooded due to over-priming of fuel or the choke has been left too open, causing too much fuel to enter the combustion chamber.
How can you tell if a chainsaw is flooded?
One tell-tale sign that a chainsaw has flooded is the smell of fresh petrol near the muffler. To ascertain whether this is indeed the problem, simply disassemble the part, pull the starter cord as if you were switching on the engine, then dry it, reassemble it and try switching it on again.
Why can’t I start my Stihl chainsaw?
Dirty or clogged fuel tanks, dirty fuel filters and lines, loose fuel hoses, dirty air filters and a dirty carburetor can all restrict fuel flow. Check, clean and replace all the fuel system parts before moving into the internal engine, as gas problems create a majority of starting problems.
Will a flooded engine fix itself?
Will a flooded engine fix itself? No. You have to take appropriate measures to restore the fuel and air balance in your car’s engine.
How long should I let a flooded engine sit?
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 won’t my chainsaw start when it’s hot?
When your chainsaw quits after it gets hot, you either have a problem with gas flow being restricted into the engine or with the spark. This is a common occurrence on older-model chainsaws. By replacing your spark plugs and keeping your gas lines clear you can reduce the chances of this problem recurring.
Can flooding engine ruin spark plugs?
In worst cases, the excess fuel can foul spark plugs, sometimes necessitating their cleaning or replacement before the engine will start.
What happens when you flood an engine with water?
Engine Damage The damage you can cause to a car’s engine by driving through flood water is nothing to scoff at. If the floodwaters are deep enough, your engine may end up ‘hydro locking,’ which, in layman’s terms, translates to “stalling” and “costly damage.”
Can you flood an engine with oil?
When excessive liquid fuel enters the combustion chamber, it can cause severe engine flooding. In addition to damage (due to excessive compression and even dilution of lubricating oil with fuel), lubricating oil can also be damaged.
