Question about Husqvarna "Chain Saw - 16" Bar, 3 Hp

1 Answer

Husqvarna 400 e series- I mixed the fuel 40-1 instead of 50-1

Hard to start. When I do get it to start it runs at 1/2 to 3/4 speed. I have drained the gas and went to the proper mixture. Cleaned the spark arrester, cleaned the plug. I bought this brand new 2 months ago. Please help. Thanks Tom.

Hi
If you have good compression and spark at the spark plug try priming the engine(put some fuel mixture in the spark plug hole),set the carb adjustment(highh speed H=3/4 turn and lowspeed L=1 1/4 turn,turn the scews clockwise until the end and then set them.Try to start the engine.If it runs only the gas you puted inside the cilinder and then stops you have a fuel delivery problem to find and fix.First disassembly ,check and clean the carb.Then the fuel filter and the hoses.Let me know. best regards savumihai71

What is the gas/2 cycle oil mixtuure for a husqvarna 55 chainsaw


These saws were normally ran on a slightly richer mix. The reason was becuase of the mix oil available. I would recommend running a 40:1 or 50:1 mix. Make sure you use an "FD" rated mix oil and Premium ethanol free fuel.
The premixed fuels / oils are even better. They contain the FD rated oil 95 octane fuel and no ethanol.

They put gas in my trimmer instead of the fuel oil mix snf now it will not start. what must i do??


Drain tank completely, pump primer to drain that back into the tank, empty tank again. Refuel with correct fuel oil mix 50:1. Hopefully if it wasn't run too much, it might not have dameged the cylinder and piston. keep your fingers crossed

What is the fuel & oil mix for a chain saw


Husqvarna chainsaws run at a 50-1 fuel oil mix with Husqvarna two stroke oil, with other two stroke oils they recommend 25-1 fuel oil mix as they do not know the quaility of other manufacturers oil, always try to use Husqvarna oil.

What oil mix ratio do i use for my huskvarna 123hd60


Husqvarna engines are made to tighter tolerances and are designed to run cooler. This is why the manufacturer recommends running a 50:1 mix. A richer mix of oil (such as 40:1) will run in the trimmer, but it will make alot of smoke, foul the spark plug, and clog the spark arrestor in a short period of time.

I recommend you stick with the 50:1 mix, and use Husqvarna, Stihl, or Echo 2 cycle mix. All three of these 2-cycle oils are a high grade oil designed to run in air cooled engines and they should not be substituted with cheaper brands

Could you please tell me the fuel mixture for husqvarna chainsaw


All Husqvarna machines are built to run on Husqvarna oil at 50-1, with the exception of the 3120XP this machine runs a 25-1 mix due to its size, always try to use the manufacturer of the saws oil , wheather it be Husqvarna, Stihl, Poulon, all manufacturers produce there own oil, they know the lubrication requirements of there machines, so what i am saying is Husqvarna two stroke oil mixed at 50-1.

I have a 1997 Yamaha 40hp....C40PLRV without oil injection. My Sealoc manual calls for a 100:1 fuel mix. I had a dealer tell me to run 50:1, but it idles rough and is hard starting when cold even with...


Mate.2 stroke motors WITH oil injection run between 100/1 and down to 40/1(rich).With yours being pre-mix,it should run at 50/1 to be safe.Using a good quality 2stroke oil,with low smoke,it should run well.The only thing that may change, is how you use the motor.Slow trolling or running along travelling.A spark plug that is 1 heat range hotter will help burn the fuel/oil mixture if you do a lot of slow running.Faster and /or high speed running,will keep your plugs ok.These are safe guides not to cook up a piston.Hope this helps you

What is fuel oil mix for the 136


Page 8 of your manual says 40:1 (3.2oz/1gal) Stihl or Husqvarna 2 cycle oil.
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 – 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

Fuel/Oil Mixture
  1. Use a quality 2 cycle oil and mix it to the OIL supplier's recommended ratio. Today I use Stihl 2 cycle oil mixed @ 50:1 in a Pioneer that I purchased new in 1980. There are no gouges or scratches on the piston or cylinder and I have no carbon build up on the piston top. The manual (on stone tablets) recommends 24:1. Over the years the mixture has leaned from 24:1 (Saw Recommendation) to 28:1 (Lawn boy mower recommendation) to 32:1 (Oil provider 8oz/2gal - used for many years) and finally the last 5 (±) years 50:1 (Stihl 2.6oz/1gal)
  2. Any fuel containing ethanol is not good with chainsaws. Mix what you expect to use within a few months. Anything over 3 months old use up in a 4 cycle engine. HTH
