Hi, my chainsaw starts and runs perfectly but after around 15 mins use, it just stops and will not start again. it seems to have the same compression and is not seized. When I go back to it the next day, it once again starts and runs perfectly for around 15 mins again. Anyone got any ideas.

ps I am using 50 to 1 mix and it is an older model 017; does anybody know if that type should be run on 25 to 1.
Thanks Steve

Have the same saw with the same problem and have been scratching my head for some time. FINALLY I think I figured it out. Check the vent on your fuel tank. You have to take off the side cover to get to it. I fixed mine and now it runs great. Hope it works for you.

check the screen over the exhaust before the muffler it could be plugged.this will cause it to have loss of power after running awhile & perhaps stop
