Hello everyone. I got a Stihl 028 AV super saw that does not work for free, from a good friend, but it is an elderly person and already has 5 saws and what each breaks, he gives it to me. To be honest, I did not know too much about saws as much as I learned the mechanics of two-stroke mechanics myself and only that my dad did not move it, I decided to start it because there is no money for service and the tree is waiting. At the very beginning, the saw had no spark, but somehow I managed to get it, the spiral was a bit wrong and it did not give a spark because it was moving from the cable. The saw, however, still did not burn, so I poured some into the cylinder and fired but went out. I decided to start the walbro carburetor, cleaned it, there were no deposits from the rubbed fuel, so I decided to pour the mixture into the cylinder again and it lit and the carburetor started to work visibly because it did not go out slightly, I adjusted it to L and H and with the boiler it was a little lacking in power, but I adjusted a little bit more and cut well. So I decided to adjust it precisely because the chain was going all the time, it accelerated well, the power was good, but I wanted to fix it and it started, dad interfered with the LA adjustments from the throttle and I started to lack power, higher and higher idling speed and I got stupid, but nothing or burned it accelerated after adding gas or it went out after adding it, I dismantled the carburetor, cleaned it, but the membranes are to be replaced and I'm waiting for new ones, this time I also cleaned the nozzles and pulled out the pump with a cone, but the carburetor does not give fuel at all. It's strange because he was surprised early and she was fun to walk and here such things happen .. and the only thing that worries me is that the idling speed is too strong go earlier when the chain was walking it was not so bad just as if but not so that it would accelerate so I preferred to put it out to it has not rubbed, I am afraid that it may be sealants on the shaft, but here is the question as if I do not know if I can change them, please give advice and possible tips on how to replace them. Thank you in advance and please help. Regards, Michał
