Elto Cub coil

[lyks2tinkr]

As usual the coil in my cub is open. I was successful in doing surgery on one in the past and we’ll see about this one.
Is there another coil that can be adapted for use?

Just recently did one.
Took longer than I expected.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

Another option for a coil is a Disston Mercury D0-100 DO-101 Chainsaw Coil. that what I used on my Cub.
As with Tubs coil, it involved a bit of cutting and grinding. Found mine on EBay.

Thanks for your efforts and posting.
They are small coils indeed.
Was thinking of trying one of those single output "miltary standard" coils. Will do some measurements

Well, exploratory coil surgery went ok.
I was able to find the broken end eventually and now have good secondary resistance.
I have a new lug made that will anchor better in the coil. The original lugs were way to small and poorly anchored and it didn’t take much to snap the extremely fine secondary wire.
I’ll post some pictures when I put it all back together.

Finally was able to put it all back together.
I made a bigger T shape lug and anchored it well.
Used dual wall heat shrink as the outside insulation.
Patience is the key when attempting to do this. The wire is so fine it breaks really easy.
Will put the mag back together and check for spark.

Was the original spark plug wire on the Cubs cloth covered or just rubber?

Thanks Tubbs. I assembled the mag today and roughly set the points. Got a nice decent spark again.
