Can anyone help me out on here? A mate gave me a 034av, he took it to a saw shop and they told him there was something wrong with the crank. Now my mate isn't mechanically minded at all so could be anything. I pulled the saw down this arvo and the cylinder was loose on the case and 1 bolt missing. I removed the cylinder which looks to be in good nick. I can get a little bit of a lean out of the crank by pushing on the flywheel and pulling on the drive sprocket, stuffed bearings? I tried starting the saw before pulling it down and could only get a fire out of it was by pouring a little fuel in the plug hole. I would have thought that if the saw pulled the jug off they would have tightened it back down and put all 4 bolts in
