I expect all 3 of mine will, but I have to give the nod to my Husqvarna 460, it sat with stale gas(ethanol gas at that, probably no stabilizer in it either) in it for 5+ years after I moved to a house with no wood stove on a lot in town so no property to maintain to speak of. It started on I think the 3rd or 4th pull, though it needed to be tuned. I pulled the carb apart and cleaned it up before I actually did any cutting with it, but I was surprised that it fired right up like that given everything I mentioned.
