the motor will not turn
, No.455 Rancher, 20″ Gas – Powered Chainsaw

Experienced gardeners share their insights in answering this question :
Remove the spark plug and see if the flywheel will turn. If it does, then there is excess fuel in the combustion chamber–install the starter and pull it through vigorously several times to expel the raw fuel. If it does not turn, then suspect that the engine has seized due to insufficient or no oil premixed into the fuel. Remove the muffler and inspect the piston, ring(s), and cylinder for excess scoring. The repair is to replace these parts–an expensive process even if you perform the labor. Any existing warranty will not cover this problem. Hope this helps!

My Z5426 won’t start. When I pull out the choke and turn the key, gas starts leaking out of the exhaust system just before it gets to the muffler. Last time it did start, it ran really rough. So, I turn off the engine and then tried to restart and that’s when I noticed the fuel leak.
ANSWER : Maybe bad fuel, fuel line leaking, flooding of the carburetor, since it did start and ran rough I am assuming that the gas was left set and more then likely this gummed up the carburetor, you will have to clean/rebuild it. If you have a can of carburetor clean you may be able to spray that into there and clean it up, I would not choke it to start it as it sounds like it got/is flooded/ing. Good Luck Tim
