I just bought the 455 rancher it is great. its not to big nor to small. i love it and it loves to kick back

 

HAVE SAME SAW FARM BOSS. PISTON FROZE UP. DEALER SAID I HAD A SMALL GAS LEAK AND SUCKED AIR. HE SAYS ITS TOO EXPENSIVE FOR HIM TO FIX TOO MUCH LABOR. HE SAID TO CHECK GAS LINES OFTEN. I MAY TRY TO REPAIR MYSELF. HOPE I HAVE BETTER LUCK THAN YOU.

 

I had the same thing happen to my Husky 55. Sucked air and burned it up. I blamed it on the ethanol in the gas. It hardens the clear plastic fuel hose and makes it brittle.

Now I've got a Stihl MS361... Love it.
