I have a Stihl chainsaw that has only about 10-15 hours of running time on it. It had been sitting in my garage for about a year and a half with old fuel. I should haven't keep the fuel in it but replaced it with a new mixture, checked the fuel filter and it was clean, and it refuses to fire. I replaced the plug in spite of the fact that the original looked ok and showed spark and it still won't start or even give an indication of firing. I then put about a tablespoon of gas in the cylinder without any hint of firing. There isn't any physical damage to it and it feels like it has good compression. The last time I did use it starting was effortless and now nothing. I'm not a small engine genius but two cycle engines aren't that complicated. Does anyone have a suggestion?
Its possible you flooded your engine with the tablespoon of gas u put in the cylinder. Let it sit for awhile with the plug removed to dry out the cylinder. Also a good idea to replace the spark plug while your at it.
Although it's about three years old, operationally it's almost new as I have relatively few hours of running time. The last time I used it starting was similar to when it was brand new so I don't think it's something such as the flywheel key. My thoughts, as suggested here, is that I'm flooding it so I'm going to give the techniques suggested her a try. One suggestion was shot of carb cleaner in the cylinder or carb and my question is if carb cleaner is similar to starting fluid? The reason I ask it that I've read that starting fluid can be pretty hard on the engine.
Thanks
starting fluid is straight either & will wash the oils off the cyl walls, carb cleaner contains oils & won't harm the cyl as long as you don't 'run' the machine off it.
It was squirting carb cleaner into the cylinder. My response was directed to Luckyvision, who suggested it, but I forgot to specify. I appreciated everyone else's help too.
