What spark plug ?

[cordy]

What plug do we use,a hot plug in cold weather,and a cold plug in hot weather ? The fuel mixture being used is 25:1. What would be a good plug for an xb stock engine? The reason I ask is because we change the electrics out right away.

As far as I know, weather is not a determining factor for which plug to use. Most people use an NGK CMR7H, but you could also use a Champion RZ7C.


Also, you will need to run richer in colder weather.
