Yeah baby.
I suggest things here to try and help folks, and try to keep them wasting a lot of time and money, etc..
Check the simple and easy stuff first, as most of the time it is just a spot of water in the fuel, or whatever.
Some of the experts here give some real bad advice, and these guys tear up there saws because of it.
And if I give a suggestion here, and it goes ignored, because folks are telling the O.P. it is a blown seal or bad coil or whatever, and gives him suggestions on how to remove a clutch/flywheel, to replace a seal that he is told has to be bad, without even testing it, well, and so on.......
I always suggest checking and testing, before going online and ordering crap.
And I always tell them how to do things properly, with low risk of them tearing up their stuff.
There is a whole lot of bad advice out there on how to work on stuff. Just because it is on A-site or Youtube doesn't make it good advice....
