Hi to all, new here. Was wondering if any of you could help? A friend has an 80's vintage JD 316. The previous owner had a 20 hp kohler twin installed to replace the original powerplant (not sure what it was) Anyway, the igniton switch was changed with the motor but the problem is this, you can turn the switch to crank and it will crank but will not fire. As soon as you let the clockwise pressure off the key it will fire, but will not fire while cranking? Apparently the JD switch would not work so whoever replaced it with a wheelhorse/kohler switch but its still not quite right.
