Hi everyone,
I have a 25 yr. old Stihl 025 I bought new. After researching here and elsewhere, I have what seems like a fairly common problem but have yet to find a good answer. It doesn't get used that often so after having carb problems I started using Trufuel and the difference in how it ran was amazing. After running perfectly it sat for about 6 mon, when I tried to start it recently I could barely pull the recoil cord and it would not start. I took the plug out and it turned normally. After research I started to diagnose things that were suggested. The plug was dry but I turned it upside down while pulling the cord and it wasn't flooded. Took the muffler off and it was amazingly clean inside, looked in the cylinder while turning it and the piston, 2 rings and cylinder wall look perfect. Took the bar, chain and sprocket off and the needle bearing, clutch and everything else looks fine. Doesn't seem to be a problem with the recoil. Read some posts about being out of time. Should I look at the flywheel and keyway next? Really hesitant to start tearing the whole thing down. I'm at at a loss so any suggestions are appreciated.
