Sure sounds like you did it all.
Was the Plug wet with gas when you took it out to fuel it directly? I would take the plug back out, blow out or let the Cylinder totally dry. Then spray a bit of Starter fluid in the carb and see if you get life.
Old gas left in a saw is a Carburetor killer. The paper components in these carbs can not stand the new 10% ethanol gas.

You may need to use a jumper wire between the threaded part of the plug and the cooling fins. You don’t have to bend up the electrode. HTH

If checking spark make shore the out side if plug is earthed to chain saw.
Fresh clean fuel, clean fuel filter filter pull exhaust off and check piston is ok. Than check for flooding. start there.

It needs spark, fuel and compression to run, which is missing?
Lets start with spark. Replace the plug (very inexpensive and great insurance), then do this:

Before we get to fuel please download and follow the start procedure in your Operator's Manual here:
HusqvarnaUSA.com
http://www.husqvarna.com/us/homeowner/support/download-manuals/
Enter the 3 digit model number (no XPs, Es, just the numbers)
Serial number decode – useful when downloading IPLs and Manuals
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week
I own a Husky 359 that 1 time I forgot to set the fast idle (close then open choke). It was near impossible to start. I have missed the initial attempt to fire and flooded it too, again almost impossible to start.

If it has spark and the start procedure fails, put a teaspoon of fuel mix in the carburetor throat, open the choke, and pull. Does it fire and attempt to start? Yes it probably has a fuel delivery problem. Please repost with what you did and we will continue. HTH

IMO regardless of what your manual says ( yours probably 50:1) all 2-cycle engines should be operated on 50:1 (1 gallon of premium fuel to 2.6 ounces of quality 2-cycle engine oil). Once adjusted for this mix they start easier, pollute a bunch less, and do not foul out plugs, cylinders, or mufflers. Run lean conditions are most often caused by dirty air filters, air leaks not detected by the operator, or failing to add any oil to the fuel in the tank. Using a 32:1 mix prevents none of these occurring! I use a Pioneer chainsaw I purchased new early 1980 with a 50:1 mix.

hi
if you have a good compression,a strong enough blue spark and carburetion for the fuel air mixture try priming the engine(put small amount of gas in the spark plug hole)then start the engine.If the engine runs only the gas you put inside the cilinder there is a carburetion problem to find and fix.

Won't start; plug looks good and has spark and it's getting fuel


Did you use the right fuel mix.? Does it still have good compression.? Have the piston rings been damaged.?
Check ignition switch.

New spark plug plus new air and fuel filter. Chainsaw will not start or even fire.


If there is a good spark and fuel getting to the plug there are only two reasons why it will not fire, sheared flywheel key knocking the timing out, or it has partly seized and has low compression.

Brand new PP4620AVX, filled it with gas,tried to start but no gas is getting to carb.


It's not getting fuel, either the fuel lines are plugged or they may be broken. Take off the air filter cover and the air filter. Check the fuel lines going into the carburator. Wiggle them a little, they may be broken and need to be replaced. Also check the fuel filter, use a 6-8", bend a hook on one end and fish out the filter from the fuel tank. It might be best to take the saw into a repair dealer if you can't figure how to get to the various parts on the saw.

I had this saw tuned up a few years ago and put it away. I added new fuel (40 to 1 mix) took out the spark plug and checked the gap.025 and didn't even have to clean it. I set the choke to full, made sure...


I don't know the plug number. Off the shelf chain saw plug from small engine repair shop will replace existing plug.

First of all, are you getting spark?
Take out plug. Put spark wire on plug. Hole plug by spark wire. Touch metal threads of spark plug to metal part of engine block. Metal to metal. Pull cord. Look for spark between metals. If there is no spark, then spark coil is bad.

Look at exhaust port. Is there anything that would stop the exhaust from escaping?

Can you get to fuel line running into carburetor? See if gas makes it all the way to the carburetor.

Can you get to the air filter? Is it dirty? Can you spray WD-40 directly into carburetor. A saw that has good exhaust, spark and compression will fire on WD-40.

If your engine can fire on WD-40, but will not stay running, then carburetor is suspect. Maybe gum out will work. Try to keep the engine going on WD-40 and see if that opens the carburetor.

If you can keep engine going on WD-40, that takes both hands ... use your third hand to move choke and throttle levers and see if the engine can start on its own.

Upvote if this information helps. Thanks for the feedback.

After starting and operating the chainsaw for a short time, it dies and I can't get it started again. Suggestions?


Engines require 3 things. Spark, compression and fuel. And chainsaw need 2-cycle oil mixed with the gas.

Assuming you have the right oil-gas mixture and a fresh batch of gas, and you didn't leave old gas in the saw all summer long since last November.

-Take off the dirty air filter and see if saw starts without filter. Do not run without putting in new filter.
-Check exhaust port for mud dobber home or screen clogged with carbon and dirt
-See if saw fires up after squirting WD-40 directly into carburetor
-Check gas line >>> pull gas line loose and see if gas flows out of tank to carburetor
-Take out spark plug > put finger over spark hole and pull cord >> do you feel suction that says you got compression?
-Put spark wire back on spark plug >>> hold spark plug so threads touch bare metal part of spark plug hole >>> pull starter cord and see if spark shows between plug and saw >>> suggest you not hold metal part of spark plug while pulling cord [you'll understand why]
-If spark plug shows spark, then your saw has spark ... so put in new plug and start fresh.

If your saw has compression, spark, and fuel it should start unless carburetor is gummed up because gas was left in tank.
Here is the final trick. Start the saw while spraying WD-40 directly into carburetor and see if you can keep it going with the WD-40. This might take a helper. If this does not work, then carburetor is bad or gas line is clogged at carburetor. Time to take it to the shop.

Can't start my Chain Saw Husqvarna 350.


The fuel may have been replaced, but is the fuel filter clean or is the fuel line cracked? Even though you cleaned the spark plug, did you check to see if it has a spark? If not, maybe a new spark plug or check the wire to make sure there is nothing blocking where the wire and spark plug connect. Is the air filter clean? Just a few more things to check out...

Have a Mac 3214, fuel lines were rotten, replaced lines spark plug and air filter. Started saw ran fine. Shut off saw, heard a girgling sound took off carb cover had fuel filling carb above throttle blade,...


The fuel metering needle in the lower carburetor chamber may have a bad rubber tip or the rubber diaphragm may be hard or cracked. McCullough fuel tanks vent through the cap (it should not have a gasket). Gravity plays no part in the carburetor fuel volume. Remove the spark plug (ignition off) and pull the engine through a few times without the choke on, but the throttle wide open to remove excess fuel in the crankcase (no smoking during this procedure). Make sure the plug is dry when you put it back. Hope this helps!

Describe your Husqvarna "Chain Saw -


Remove the spark plug and test for spark. If ok, try some starting fluid in the plug hole, install the plug, and try to start. If it runs a short time, it is not getting fuel. Check fuel lines including inside the tank. Clean or replace the air filter. If this saw is fairly old, the carburetor probably needs a re-kit and cleaning. Does it have good compression? Check the muffler for plugging. Make sure the fuel/oil mix is fresh. Good luck!
