HELP! Anyone have a junk Echo CST-610 twin coil?

[EFSM]

I have an Echo twin-cylinder CST-610 that I'm desperate to get running. I found an issue with the original coil, but I think I had already damaged it otherwise before finding the loose connection at the ground to the laminations. The first picture is the resistance from the kill wire to the laminations if I pinched the coil body at that particular spot. Without pinching it the resistance was way out of spec. I fixed that but I had already been grinding on the potting to try to expose the issue and I may have messed something else up.

I'm wondering if anyone has a bad coil that I could buy and see if I can repair. I'm willing to pay shipping plus something for the coil. Thanks!

I cannot help with a spare coil, but I can report on what I found on the JD version of that saw I acquired this year. I am measuring from the spark plug lead to the primary wire with the meter set on the 2 K scale so call it 1.2 K ohms +/-.

The coils for the EVL-610 and the 66-SV counterpart are notorious for browning out and having other issues. I doubt that little bit of grinding you did ruined the coil. If it's not working it likely had issues before that.

Found one on eBay that I snapped up before the listing was more than a few hours old. Fingers crossed that it works…
I wish I didn’t have to spend almost 2 bills on a used coil, but it’s the only one I’ve seen listed in my many months of watching.

Is that gold plated?? Platinum dipped?? Ouch...hopefully it is a rock solid coil and you are able to get your saw up and running again!!

Coil parts for the 610-EVL and 66 SV almost never come up on eBay. I think I've seen maybe five sets of coils on there in the last 28 years.

That’s a bargain compared to some of the prices I’ve seen on old adds.

No kidding. This is the first set I’ve seen for sale anywhere.
