Chasing intermittent loss of spark. Have tried almost everything.
Have identical ski also to swap over parts. Was swapping over the black ignition boxes this evening. I notice the there was a difference the fitting of the ign coil.
That is on one set wire 1 was feeding coil to mag cylinder. On the other set wirev1 was feeding the pto cylinder.
Anyone know for definite which coil feeds which cylinder.
