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.

Re: husqvarna 400 e series- I mixed the fuel 40-1 instead...
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

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.
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.
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.
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.
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
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)
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
