How to start a Chainsaw that won’t Start- Final Thoughts on Troubleshooting a Chainsaw

If your mornings have ever been punctuated by the frustrating sputter of a chainsaw that simply refuses to come to life, you know the feeling all too well.

The seemingly endless pull on that start cord, the sense of dread creeping in as you realize your trusty tool might not be so trusty anymore – it’s an experience no one relishes.

Welcome to our comprehensive guide titled ‘How to Start a Chainsaw that won’t Start.’

We understand just how crucial this equipment is for those epic woodworking projects or routine yard maintenance tasks, and when it decides not to cooperate, everything comes grinding to a halt.

So before you resign yourself to costly repairs or even consider replacing your chainsaw altogether, let’s take a closer look at some simple solutions and techniques designed specifically for these stubborn situations. Get ready to rev up that silent saw back into action!

Understanding Chainsaw Starting Problems

Understanding chainsaw starting problems can sometimes feel like a detective story, with clues to be found in smoke signals or unheard whispers of an overfed carburetor.

But fear not, dear readers – realizing the complex puzzle of chainsaw-starting woes isn’t nearly as daunting as you might think. Essentially, it hinges on three key elements: fuel, air and spark.

If your chainsaw is being stubborn and refuses to roar into action, don’t just give up and assume it’s off for an eternal nap.

Quite often the problem lies somewhere along these vital lifelines.

Too little or too much fuel; a blocked air passage or an ineffective spark could hinder the whole process from kickstarting!

Something as trivial as old gas in your tool could also lead to starting hiccups – making checking the condition of your fuels since last use crucial!

Plus remember ‘the balance’—strategies that strike a harmony between idling speed and enriched mixture adjustments work best.

Necessary Safety Measures Before Troubleshooting

Before plunging into the mystery of your non-cooperative chainsaw, you need to consider some important safety measures. One can easily forget how unpredictable machinery can be when we’re engrossed in troubleshooting an issue.

Proper protective gear such as safety glasses, gloves and sturdy footwear should not be dismissed lightly.

Not only for personal protection but also to ensure a smooth trouble-shooting process without being hindered by accidental injuries or discomforts.

Additionally, make certain that your environment is suitable for the task at hand. Clear the vicinity of unnecessary clutter which might distract you or potentially cause mishaps.

Always remember, handling a gasoline-filled machinery requires utmost care to prevent flammable accidents and injuries.

The marriage of focus, determination and dollop of caution sets up an ideal scenario empowering your success in reviving that dormant chainsaw!

Steps to start a chainsaw that won’t start

There are numerous reasons that your chainsaw wont start. So you need to check upon every single element to start your chainsaw.

To gracefully transition your chainsaw from a stubborn piece of metal to a lively machine, it’s essential to assess the step by step below mentioned steps-

  • Take a moment to check the chainsaw’s fuel pot.
  • Dusty or stale fuel can prevent your tool from starting as easily as you’d like it to. Remember: a healthy blend boasts an ideal mix of gasoline and oil— typically 40:1 or 50:1 ratio—providing the perfect lubrication for internal components while generating sufficient power.
  • If you suspect that old or contaminated fuel is restricting your lumberjack dreams, have no fear!
  • Replacing questionable gas with fresh stock immensely improves your chances at hearing that powerful roar once again.
  • Most chainsaws have a primer bulb. Press it several times to ensure that fuel is reaching the carburetor.
  • Set the choke to the proper position. In general, when starting a cold engine, the choke should be engaged. If the engine is warm, the choke should be disengaged.
  • Confirm that the ignition switch is in the “on” position.
  • Pull the starter cord with a smooth, controlled motion. Don’t yank it forcefully.
  • Check the spark plug for fouling. If it’s dirty or fouled, clean or replace it.
  • A clogged air filter can prevent the engine from starting. Clean or replace the air filter if necessary.
  • If the engine has low compression, it may not start. This could be a more serious issue and may require professional attention.
  • Ensure that you are using fresh and clean fuel. Stale or contaminated fuel can cause starting issues.
  • Check the fuel lines for any kinks, cracks, or other damage. Replace damaged fuel lines.
  • If none of the above steps work, there may be an issue with the carburetor. This may require more advanced troubleshooting or professional help.
  • If you’ve gone through these steps and the chainsaw still won’t start, it might be a good idea to consult the user manual for your specific chainsaw model or seek assistance from a professional technician or the manufacturer’s customer support.

Professional Help or Chainsaw Replacement Decision

At some point, you might find yourself at the crossroads of decision-making: Is it time to seek professional help for your disobedient chainsaw or should you consider replacing it?

An element of practicality that filters into this deliberation is cost-efficiency.

If repairs continue to bleed your wallet and temporary fixes are becoming a recurrent theme, then perhaps it’s prudent to analyze whether investing in a new chainsaw would eclipse the accrued repair costs.

Your chainsaw should be a reliable tool, spurring up with a hearty roar whenever duty calls. If frustrations persist after countless DIY techniques, rightly judge that it’s high time you rocked down the ‘expert intervention’ avenue.

Getting professional help will not only ensure an accurate diagnosis but possibly save you from future mishaps by identifying clearly any systemic problems.

On the other hand, total replacement ushers in fresh technology benefits including increased efficiency and safety features; whilst breaking free from otherwise stubborn and persistent issues reminiscent of your old chainsaw.

It’s all about weighing these factors keenly before making an informed decision.


In essence, troubleshooting a non-starting chainsaw can seem like an uphill battle.

However, realizing that the devil is often in the details, breathing life back into your tool could be as simple as changing out a spark plug or tweaking the carburetor settings.

The delicate interplay of fuel flow, air intake and ignition that powers these roaring beasts naturally necessitates some finesse and patience.

The real takeaway here is: do not give up on your chainsaw when it refuses to start.

Gain solace from demystifying what seems like an insurmountable issue into manageable checks and fixes you can handle yourself!

You’ll not only save money but also secure an invaluable set of skills for further equipment maintenance endeavors down the line – skills that speak to self-reliance and resilience in handling such robust machinery.

Q: Is there anything I can do to prevent starting problems in the future?

Regular maintenance of your chainsaw will help prevent starting problems. This includes regular cleaning and timely replacement of worn-out parts like filters and spark plugs.

Q: Can cold weather affect my chainsaw from starting?
