Hello everyone, I'm new to this site. New to wood burning and chain saws. I have a Stihl 046 that runs great and a 034 that barely runs at all. The only way I can get the 034 started is to pour some gas into the cylinder then hurry and put the spark plug back in. Once it starts it runs great for about 1 minute. Then after a minute it will idle fine but as soon as you hit the gas it boggs down. Does anybody have any idea what is wrong?
