Question about Husqvarna Chain Saw 20" Bar

1 Answer

I have a Husqvarna 455 about 2 years old. At about 1 year point it would no longer start using the primer pump button on the side when cold. If I take off the air cleaner and give it a a shot of gas down the carb throat it starts right up. I can see the gas ( and air bubbles) moving through the clear lines to the primer pump so the pump /check valve seems ok? what next?

Your seeing the problem. Air in the fuel lines usually caused by a cracked fuel line or a pin hole in the primer bulb. Until you can stop the air bubbles by either replacing the actual primer bulb or fuel lines your always going to have the hard to start problem. This can also cause the engine to run lean at high RPM settings and eventually burn a hole in the piston. You should repair the fuel problem ASAP. If you do not find any fuel line / primer bulb problems then it is time to start looking at the carb diaphram.

Husqvarna 455 rancher new filters /plug get spark wont start put gas in cylinder and wont start what am i missing


Check to see if there is a leak in the air purge bulb (primer bulb), sometimes they crack and allow air in and don't push the gas through properly. Here is the manual for your saw.
Cheers!

I HAVE A HUSQVARNA MONDO LINE TRIMMER.WHERE DO THE FUEL LINES CONNECT.THE MACHINE HAS A WALBRO CARB.


For a machine with a remote primer bulb: The small diameter line out of fuel tank (has filter in-tank on end) connects directly to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then "pushes" any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. This is the return line. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb. For a machine with the purge/primer bulb on top of the carb: The small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so.

Fuel ratio 50:1 = 1gal premium/2.6oz quality 2-cycle engine oil
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 2gal premium/8oz chainsaw 2-cycle engine oil - used for many years) and finally the last 5 (±) years 50:1 (1gal premium/2.6oz Stihl 2-cycle engine oil)
  2. Any fuel containing ethanol is not good with chainsaws. Mix what you expect to use within a few weeks. Anything over 1.5 months old use up in a 4 cycle engine. HTH
