    40:1, make sure you are using Husqvarna recommended oil, it does make a differance in performance, and how long the unit will last.

All Husqvarna products for at least the 5 years are 50:1. As are every manufacturer with the exception of Poulan which is 40:1. If you are going to provide advice PLEASE take a few minutes to ensure it is correct! HTH

What is the gas / oil ratio mixture for husqvarna 455 rancher model ?

50:1 that's 2.6 ounces of 2-stroke oil (preferably with fuel stabilizer) to one gallon of gas. I recommend using 89 octane gasoline for all small engines. It has little or no ethanol in it, as opposed to the 10% typical in 87 or 86 octane fuel. This will prevent a lot of fuel issues, especially if you are not using the tool daily or at least weekly.

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.

I have a Husqvarna 455 Rancher - about 1 month old. Worked perfect one day. Would not start the next. Feels like there is no compression. Second 455 with this problem.

There is only two reasons for low compression, either the piston ring has gummed in, or the piston has seized, remove the muffler and check out the condition of the piston skirt through the open exhaust port, any signs of scuffing and the piston has seized, it will then need to come apart to see how much damage has occured. Saws today are set up very lean on the mixture to get the best emmissions not the best running, they realy need to be using the very best two stroke oil.
