I'm hoping you guys can help me out here a little bit. I recently picked up a 1981 110 from my uncle. Wouldn't start from the get go. I resealed the top end and installed new valves, replaced fuel lines, and main ignition coil. Problem I'm having is, I can't get the thing to even fire. It will pop once and a while but isn't even coming close to firing and running. I've tested the stator, pulse generator and coil and everything checks out. I have a new plug in and have good spark and compression. Even shooting some fuel into the cylinder and cranking it over does nothing.
Only thing I can think of is timing. I made sure the cam sprocket was in the correct position when I replaced it and I'm fairly confident that end of it is correct. Valves were adjusted to spec when replaced. What I'm wondering is, would bad springs in the mechanical spark advance cause a no start? The springs seem really stretched out and the lobes are pretty loose. I have a motor from a 1980 110 (points no CDI). Are the mechanical spark advances the same in them?
Thanks,
Jon
