My Husky Rancher 455 has needed at least 5 pulls from the day I bought it to start from cold. Warmed up its better. It runs great, idles well and overall I am very happy with it. I am comparing it to my old HD $99 special McCullough saw that started on the second pull every time. Yes I do use the decompression button and the primer bulb and choke it properly. I have changed the plug and filter already and checked the plug gap. I use the specified mix of synthetic oil. Is this just typical for this saw?
