Hi everyone, I bought this stihl used a couple of months ago and just started using it. It runs great till I get it warmed up and maybe 1/3 way threw the tank, then it starts bogging under full speed while cutting. It will idel fine and still cut. I have rebuilt the carb, replaced the plug, ran a tank of stihl synth oil mixed with 93 octane gas. I love the saw and want to get it running perfect. I also looked at the piston and it looks great. How do I check the fuel vent? Anyother suggestions?
