Honda ignition problem
my cousin has a 20 hp? Honda in his Melroe side by side. and when it gets to -20 below in Mn. One plug fires good but the other doesn't I have to set the gap on the plug just about 3 hairs thick to get it to run, When it warms up outside, the spark is back to normal, he said the ign system has one coil with 2 plug leads going to the plugs. So that elimates a bad coil, I replaced the Plug end of the wire, and that is a copper core, any idea's?
