Can cold weather affect the spark on my Toto walkbehind lawnmower?

I;ve checked for worn wires that might be shorting the electricalsystem and removed the wire from the magneto connected to the flywheel braking switch and still no spark. The machine was running fine in September when the weather was warm.|||You didn't say how old your machine is,or what brand engine it has. So we don't know if it has breaker points or not. Going on the assumption it indeed has points, replace them. If it is breakerless The coil (module) must be replaced. I suggest you go to this site and enter your engine model %26amp; spec #. This should tell you if your engine has points or not.

Look for oxidized points(oxidation is like rust but not example pennies oxidize and go from shiny metallic copper to dull not so mettallic finish. Points get spark arcing accross them and will lose their shine quickly and also lose the conductivity needed to carry the current for the spark plug. That or the ground has been lost which is neede to complete the circuit.|||the magneto magnet in the flywheel may have rust on it, and not allowing any spark. Had that happen one time.. Used steel wool and got the rust off and it started right up.
