Crank Starting a Chainsaw - Starting a Flooded Chainsaw


3 of 3

Flooding is the Problem - Turn Engine On
Flooding is caused by too much gas applied at the wrong time and can prevent a saw from starting. Flooding is the major cause of a stalled chainsaw engine. As previously instructed, everything should now be turned off.

The rebooting instructions in step #2 should improve this condition. Another suggestion loggers make is pulling the engine's cord through 8 times with all systems off. I don't know if this actually helps drain the liquid gas or gives a bit more drain time but I am assured it works. Do it 8 times! Then, without priming, try restarting with all systems on.

Now. Set the on/off switch in the "on" position. The throttle "on" position should be turned on only as a last resort. Actually, I am told some late-model chainsaws specifically instruct you to tweak the throttle - so do it if instructed. Put the choke to the "on" position. Everything should be back on.

Now that you have cleared the engine of too much "liquid" gasoline and setting the choke in the "on" position, pull the engine cord several times through until the engine "pops" one time. A pop is a quick audible response and jerk by the engine without cranking. Please, NO more than one pop with choke on or you risk another fatal flood.


With the choke in the off position, pull the engine's crank cord through again. The engine should start in 1 to 3 pulls. Try it first without using the throttle control (unless recommended by the manufacturer).

Colder weather or a saw just out of storage can complicate these instructions. Here is further advice from an About Forestry Forum poster: "If I haven't gotten a pop in four pulls I transition to the part throttle, no-choke position and if I haven't gotten a start in maybe 8 pulls I return to the choke position for one or two pulls. I am sure this varies with different chainsaws, but you shouldn't have to pull very many times in the choke position, even in cold weather."
