Take the saw outside and have a fire extinguisher handy.

SCENARIO #1)
With the switch in the OFF position, remove the spark plug and SLOWLY pull the rope.
CAREFUL HERE!
If you notice raw, liquid fuel coming from the spark plug hole you have a fire hazard in you bare hands!

Gradually increase pulling speed to see if you notice any fuel vapors or mist coming from the spark plug hole. If you do, you have found the problem: It's flooded.
Continue pulling rope and use an air blow gun to LIGHTLY blow into the spark plug hole and dry the cylinder. You should pull 20 or 30 times while blowing air in.

SCENARIO #2)
If the cylinder is bone dry reattach the spark plug wire to the plug and touch the outer shell of the plug (or the threads of it) to a metal surface on the saw's engine (AWAY from the spark plug hole!) You can use any metal object to conduct the electricity and increase your reach if needed. Turn the switch back on and pull the rope medium speed and check for spark on the electrode of the plug. If no spark, turn switch to other position and repeat.

NOTE: IT WILL NOT SHOCK YOU as long as you maintain contact with the outer shell of the spark plug and the engine's metal parts.
If spark is present, reinstall plug and try again.

Be sure the choke lever is set properly for either cold or warm starts (whichever applies) and it should start easily for you in the future.
Hope this helps!

I put regular gas to my ryobi c4620. Chain saw. And know it won't start I check tne spark plug has spark I put mix gas still won't start is there something I can do to get this chain saw to start


when you put un mixed fuel into a tool that needs to have mixed fuel/oil (the oil acts as a lubricant) and the tool will run on no lube for a little bit but it quickly damages the rotating metal parts inside the tool , most times the cylinder/piston is the most effected by this , ive replaced a few pistons when this occurs , and sometimes it allows it run again , but its never as good as new again

Ts410 stihl saw stopped working


Starting procedure for Stihl.
(cold starting)

Place cutoff saw on floor (flat clear surface).
Hold throttle in, while pushing on switch all the way down.
Hold cutoff saw firmly.
Pull starter handle until saw fires, it should then cut out.
Click the starter switch up 1 click to half choke.
Pull starter handle again until cutoff saw fires up. note: it will be reving because the trigger is loched on, (blip the throttle once) and it should go to tick over.

There should be np need to keep playing with the choke when the saw is warm. No need to lock the trigger when starting warm..

Husqvarna 372xp won't start... Mysterious


I recently bought a brand new 372XP and spent the first day trying to start it as per the instruction manual with no success, never even fired once. Removed the plug to find plenty of fuel and that the plug has a good spark. Left it until the next day mainly to allow my arm to recover (& scour the internet for clues). I found a forum that said not to use the decompressor and sure enough without the use of the decompressor button it fired first go with the choke on then I reset the choke & it ran properly on the second pull. The decompressor button can be reset with fine nosed pliers or removal of the top cover by undoing three screws. Good luck it's a great saw once you know how to start it.

My recondition saw wont start. It was used only once. Are these saws known to be mellons?


Check with you dealer for the proper fuel mix. After the right fuel, remove the fuel filter and give it a shot of starter fluid. This should at least let it fire. Also make sure the fuel line hasen't come off.

Back fires and rough engine


Drain your fuel tank first. Then mix 50/50 parts mixing oil and fresh gas. Put fresh gas into the saw as well as putting in a new spark plug and start it up. Stale gas (gas that has sat in the tank or gas jug for an extended period of time), bad gas or water in the gas will cause it to rough idle and back fire.

It's possible the brake is on. Try pushing the brake forward then pulling it back until you hear it click. Then try cranking it again.

Will not start. Has spark, gas,chain oil,on/off


If everything you say is true it is flooded. Have you tried the EXACT start procedure from the manual?
My 359 floods in a nano second if I leave the choke engaged once it attempts to start. The only other time it really gave me trouble was one time I failed to set then turn off choke when it was warm. Setting the choke also sets the fast idle. Pulling the starter with choke engaged floods it once it has fired. This should be similar to your Operator's Manual.
Start Procedure
Cold:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4)
  4. Set compression release – optional step even if saw is equipped with a compression release
  5. Push (open) choke pull starter until it starts. (usually first pull)
Warm:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) - Don’t pull with choke closed.
  4. Push (open) choke, pull starter until it starts. (usually first pull)
Incase you've misplaced your manual:

Enter the 3 digit model number (no XPs, Es, just the numbers)
Serial number decode – for use with IPL
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week

New 445 husqvarna chainsaw will not start


Drain the fuel tank, look inside the tank to ensure that the fuel line inside still has a fuel filter attached to it.
Look at the on/off switch ensure that both the wires are still attached to the switch securely.
Check that the plug still has spark, if unsure replace the plug.
Check the air filter to ensure that it is clean.
Mix the gas 50:1.

Will not start - brand new


i bought a new dirtbike as a kid n same thing.it turned out ,it needed to be a synthedic oil in the mix.try seeing for spark to begin with by putting sparkplug in the wire n touching diode to the engine block while pulling the cord.thats a good starting point to diagnosing your problem.maybe try warming it up in the house then try starting it with no choke needed.the saws i ve used needed you to give it throttle after you pull,n no throttle with choke.
