Craftsman 18' 42cc chainsaw won't start but has spark
I am seeking some help with a craftsman chainsaw. I don't know what model it is. I haven't looked closely for it but it doesn't appear to be real obvious either. The saw came from an auction so i don't know the history of the unit. It wouldn't start when i got it home, so I began the diagnosis process. It has spark when the plug is taken out and grounded, however, I have not been able to get it to even pop off on starting fluid.
I found another post for a guy that said perhaps it was not sparking at the right time, possibly due to the fact that the key on the flywheel was sheered off. I took mine off tonight and everything looks great there. This saw looks like it was barely used.
They suggested that I take off the muffler as well and make sure the piston wasn't grooved from running too lean. As best i can tell it looks ok to me, though i'm not experienced with small engines. It has good compression, so i am at a loss as to why it wouldn't atleast fire up for a second with the starter fluid.
I would greatly appreciate any other ideas or possibilities that i could try. Thanks in advance,
