Pop the caps out, a T27 will remove the screws and pull the tank back from the engine/crankcase.Never going to find what`s wrong looking at those picts.
If you have not taken them out already there should be a T27 screw in each of those AV bushings attaching them to the tank and wishbone. I use a scrench and gently push it in between the metal and the rubber and pry out.
Handle bar bent...should have looked the bar over inch by inch and I did not. There was a lot of torque on this bar and it twisted the back cover of saw. It still will not go all the way back into place but so much better.
Thanks
