Help, I just picked up another 3400, a very clean one. I was told it had a fuel problem and would not start. I checked it out when I got home and compression was good but no spark, ahh bad coil, then flipped the switch the other way and got a spark. The switch was in the opposite way, could be why he couldn’t get it started. I have it running and carb adjusted, runs great but it does not seem to have the correct bar or the oiler is not working or both. I read back in the thread about another oiler situation which helps me understand it as a whole, but bars are confusing to me and found nothing that’s helps on that subject. In the photo the top bar is what I took off this 3400. The middle bar came off a 245A and is the one I want to use on this 3400 I just got, it’s a 20”. The bottom bar is what came off another 3400 I have, its 16” and looks OEM to me but not one you can flip over, no small hole on each side. Will the 245 bar work on a 3400? Does it look like the top bar is the wrong bar (it does to me) all together? With the cover, bar and chain guards off and the saw running\revving, should oil be coming out of the hole because it doesn’t seem too unless it is extremely small amount I don’t notice, the manual oiling does work? So do I have a bar problem, oiler problem or both.
