champion 2J

[JEFFREY PLITT]

well i need help again . just landed a real clean champion 2J . no spark , coil has many cracks and crumbling . its a cylinder shape held on by clips . any ideas on a replacement ? thanks in advance

Here’s what the coil looks like in case anyone is wondering.
I did not have to replace the coil on mine. Perhaps an OMC
coil retrofit would work on this single cylinder engine?

Appears to be an early Bendix Scintilla ignition. I know coils are available and look the same but wires come out on one side. Condenser is more of a challenge but can be made.

You can relocate the nub where plug wire connects.

Old Bendix vs. New conversion…….copper foil tape glued & soldered to a properly located solder tab for the plug wire ….two wraps with electrical tape and sealed with corona dope……easy and cheap

[Buccaneer]

KirkP, interesting about the copper foil used. Is there a benefit in
using that rather than soldering an insulated wire from the
original secondary post to the new one, other than it would
be a little thinner?

Buc, I personally have not done this conversion but have been following discussions on another board. It was stated that using wire was difficult due to clearance issues. Here’s something another person wrote. “I got a piece of K&S brass strip about 1/4″ wide. I bent it to fit the contour of the coil, soldered one end to one of the little solder terminals on the side and JB Welded the brass strip to the side of the coil.”

I’ve also heard of someone using heat shrink.

Hope that helps

Condenser, too, is easy. Use one like this:

Long live American manufacturing!

You may all have seen this but here’s a recent post about using the military scintilla coils and dealing with the offset solder posts. Check out the pictures. Pretty slick.
