In my flock I have one EFPC, my only electronic ignition model. Currently working but the HT lead, (spark plug wire?) was electrical taped and feels weak and very jury rigged. Worry about its' longevity. How do you replace it? Doesn't look as easy as the older set up.
Thanks

Well first you will have to find some 5mm copper cored sparkplug wire.
Then remove the recoil starter, recoil starter cup & spacer, & the flywheel cover, if your flywheel has a groove on the outer face about 10mm up from the bottom edge, put it back together as the HT lead is not renewable without getting an exchange brown CDI from John at SOS.
With a smooth outer circumference your CDI should be a white one.
remove flywheel in the normal manner, but with more care than usual as these flywheels are cast from a material akin to Marzak i.e, very easily damaged, then unbolt white CDI unit & remove from base plate, the HT lead will then unscrew from the bottom of the HT coil. Larger than 5mm plug leads will NOT fit.
Do not attempt to exchange the CDI unit for one of a different colour without changing the flywheel at the same time.
CDI units are only available on an exchange basis, so don't throw damaged ones away as John carries reconditioned exchange units.
Make it idiot proof and someone will make a better idiot.
Thanks Charles,
Your description is clear and helpful. I'll attempt this repair in the off season as my boat is on a mooring and the season in Minnesota is a rather short one. I'll let you know how it turns out.
Thanks again

Hi Charles
Followed your directions...ran into something peculiar, perhaps? The flywheel had stamped on in century 102. It has the smooth edge that indicated the ht lead could be changed just didn't know about the century 102 flywheel and what that might mean if anything.
Any help would be appreciated.
Thanks

Hi Charles,
I agree with the if it ain't broke...unfortunately it did this past weekend. This is a 79' EFPC, with the smooth flywheel; no groove. If I understand your first reply this should be the one that allows "replacement" of the wire only -- I have found a source of 5mm copper spark plug wire. Have I misunderstood? Your valued guidance would be appreciated...I'd like to proceed with the operation but this is my first surgery of this type other than removing the flywheel on a 73' wspcl.
Please advice with any details and trepidations you have.
Thanks
John
