Got the above saw in great shape ,even got the yellow case for it. The saw was running good but the other day ,. i tried to start it and it was lock up. pull the spark plug and the crankcase was full of bar oil. My question what would cause this .I know its probably a check valve buts you all know there a pita to work on. what would cause this?
