Watch: How to Un-Flood a Chainsaw Without Tools
Russ Chastain 06.29.18
Flooded carbs are one of the most aggravating things about small 2-stroke engines, and are perhaps the most common ailment they have. And 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 first step is identifying the problem, and if you have been pulling that rope for a while with no results and you have good spark, the carb is probably flooded. 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. But what if you left the spark plug tool at home or in the truck and you’re out in the boonies? Well, you can either do what I’ve done in the past (become irate and fling your saw as hard as you possibly can), or follow this guy’s directions.
I can guarantee that this guy’s method is safer for your saw, your wallet, and possibly your blood pressure.
What he does is keep the choke off, hold the throttle wide open, and pull like a madman until it finally starts up. 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.
If this method doesn’t work, find a tool and try the usual method. If that doesn’t work (I currently have a hedge trimmer that stays flooded no matter what) you have a carburetor problem that will have to be fixed.
Small engines can be frustrating, but once you know what to look for and how to deal with the symptoms, things become a lot less infuriating.
Here’s the video. You’re welcome.
