Which a socket and wrench.How did you re-tighten the flywheel nut?
I can say that there is spark when I pull the plug out, connect spark plug wire and I can see it firing when I pull rope. I also used a spark plug tester that showed I was getting fire.If it was running when you took it apart and now does not run when you put it back together, you obviously didnt put it back together right. Until you tell us how far you took the saw down, we can only "pot-shot" what may be wrong. You said it would not start or cough on starting fluid. That tells us no spark(coil wired wrong) or spark at the wrong time(sheared flywheel key). Until you start testing as was advised earlier, we can't be much help.
How do you know?It's not sheared.
Because I checked, again.How do you know?
Yes. Crankshaft.The sprocket should turn freely if the saw is not running. By "drive shaft" I think you mean crankshaft. I believe this saw has a slot in the flywheel and in the crank shaft and the key is separate. The taper on the shaft is what locks the flywheel to the crank so if the flywheel is bolted on, the crank shaft should turn. The key is what locates the flywheel on the crankshaft for correct ignition timing. As already mentioned, check the gap between the coil and the flywheel by inserting a business card between the two and then tightening the coil mounting screws - should be a gap of about .010". Have you tried priming the carb with some mixed fuel? Is there fuel in the tank and is the fuel line/ filter submerged in the fuel? Is there any damage to the fuel line? Did you install a new gasket or use some sort of sealer? If sealer clogged the impulse passage the carb won't pump up any fuel from the tank.
Good.... Just so you checked again.Because I checked, again.
Opened plug to 1/4 inch, it's basically setting at a 45 degree angle. The spark jumps to the sides of the electrode instead of tip now. (Path of least resistance or just plain shortest distance). My wife said she thought a couple made it to tip.Take a test plug and open gap to about 1/4 inch, will it spark then? More compression requires more voltage. You could have had a weak ignition, and the extra compression sent it over the edge.
My wife says that to try to make me feel better....Opened plug to 1/4 inch, it's basically setting at a 45 degree angle. The spark jumps to the sides of the electrode instead of tip now. (Path of least resistance or just plain shortest distance). My wife said she thought a couple made it to tip.
Sounds like it is the latter model, and the oil lines have put oil in the engine, or the carb is flooding.Replaced oil case housing due to broke handle bracket. Put back together and it will not start. It for sure feels to have more compression.
I have replaced spark plug and verified that it is sparking.
Will not fire even with starting fluid.
Don't know what else to try.
