Why Is My Chainsaw So Hard to Pull-Start?

By

A chainsaw hard to pull start is usually one of four things: it’s flooded, you’re yanking from the wrong spot, the starter rope is worn, or the saw simply has more compression than your shoulder wants to fight. The first three you can fix. The last one is why easy-start systems and decompression valves exist.

This page is about the pull itself. If the saw pulls fine but never fires, that’s a different problem, and my Stihl chainsaw won’t start guide covers it. Still choosing a saw? My gas chainsaw buying guide says what to look for in the starter.

The hard part, said plainly

A gas saw has to turn the engine over against its compression to start. Stihl’s own Easy2Start page describes the job as pulling the starter grip to overcome engine compression. On a regular starter, that’s a firm, quick pull, and for a lot of us it’s the worst part of owning a saw.

From my land

I’ve used Poulan saws at work, and starting them was my whole problem. We called them “Pullin’, pullin’, pullin’.” That’s why my everyday saw today is a Stihl MS 251 C-BE with easy start. I’m not getting any younger, and pulling a cord really isn’t my favorite thing to do.

1. It’s flooded

Every extra pull on a flooded saw is wasted work. Stihl says the most common reason a saw floods is “too many attempts trying to start the machine in the choke position,” and that pulling more than two to three times on full choke may flood it. Stihl’s fix is to move the lever to half choke or part throttle, which lets more air in. Stihl says to move off full choke after three or four pulls even if the engine hasn’t fired.

Flooded engines make me crazy. On my saw, one or two pumps of the primer bulb is all it wants; more than that floods it.

2. The way you pull

Husqvarna’s starting steps say to pull the starter rope slowly until you feel resistance, then pull firmly. Starting the stroke from slack wastes your strength on rope you didn’t need to move. Its steps also say to press the saw’s body to the ground with your foot through the rear handle and your left hand on the front handle, so you’re pulling against the saw, not lifting it.

On an easy-start saw it’s different. Stihl says with Easy2Start “an even pull with two fingers is sufficient,” and the rope “can be pulled approximately two-thirds slower.” If you’re yanking an easy-start saw like an old one, slow down.

Safety

Husqvarna’s starting steps begin with the chain brake engaged and end with releasing it. Its steps start the saw on the ground, with a firm hold on the front handle.

3. The starter rope is worn

Husqvarna lists the signs that a pull cord needs replacing: a damaged handle, a rope that is thinning, the wrong cord length or diameter, or sap and dirt built up that won’t clean off. Replacing it is a small job. If your saw is still under warranty, the dealer is the safer call.

4. It’s hot

A saw that starts fine cold but won’t go again after a hard run may have vapor lock. Husqvarna’s fix is to put the saw in a cool, shaded spot for at least 20 minutes before you try again, then follow its hot-start steps.

5. It pulls too easily, which is its own problem

If the rope suddenly pulls with almost no resistance, think compression, not strength. Husqvarna’s test: set the saw on the ground and lift it by the starter rope. If the rope slowly pulls out, compression is likely low, from air leaks at the crankshaft seals or a damaged piston or rings. That one goes to the dealer.

When the real fix is a different saw

If your saw is healthy and the pull is still too much, look at the starter itself:

  • Stihl Easy2Start: marked with an “E” in the model name, like my C-BE.
  • Husqvarna Smart Start: Husqvarna says it’s built “for easy and fast starting with minimum effort.”
  • A decompression valve: on the Husqvarna 460 Rancher, Husqvarna says it “reduces the force needed to pull the rope by roughly 50%.”

My easiest starting chainsaw guide walks through sizing a saw to you and your pull. And for little jobs near the house, I grab my Saker 22-volt mini saw. No cord at all.

What I do myself, and what goes to the dealer

My habit: I replace the spark plug, air filter, fuel filter and primer bulb myself, twice a year at most, and the air filter most often. That’s mine, not a maker’s schedule. My Stihl MS 251 maintenance guide has the parts and Stihl’s intervals. Low compression, a starter that binds, and anything under warranty go to my local Stihl dealer.

The bottom line

A chainsaw that’s hard to pull-start is usually flooded or being pulled from slack. Move off full choke after three or four pulls, go easy on the primer, take up the slack before you pull firmly, and let a hot saw cool. Replace a worn rope. If the saw is healthy and the pull is still too hard, an easy-start system or a decompression valve is the fix, not more muscle.

Chainsaw hard to pull start FAQ

Why is my chainsaw so hard to pull?

The engine’s compression is what you’re pulling against. Flooding, starting the pull from slack, or a worn starter rope make it worse. Stihl says flooding usually comes from too many pulls on full choke.

How do you start a chainsaw that is hard to pull?

Husqvarna’s steps: chain brake on, saw on the ground, foot through the rear handle, then pull the rope slowly until you feel resistance and pull firmly. Move off full choke after a few pulls so it doesn’t flood.

Why is my chainsaw hard to start when hot?

It may be vapor lock from overheated fuel. Husqvarna says to put the saw somewhere cool and shaded for at least 20 minutes, then try again.

How can I tell if my chainsaw has low compression?

Husqvarna’s check: set the saw on the ground and lift it by the starter rope. If the rope slowly pulls out, compression is likely low, and the saw needs a repair.
