The latest ipl of the 076, shows the two different carbs and the extra spacer and different air filter surrounds because the super ran an extra 1/2” spacer and walbro carb vs the tillotson of the 075 and standard 076

You could always test the ignition and retrofit it with a module

I’m sure one out of a ts 760 would work also they are limited rpm but still same set up

Have you found a solution for your lack of spark? I fixed up an 076 Super a few years ago. Its main problem was no spark. The coil seemed to test ok so began searching for a replacement trigger plate. Mine has the doughnut-shaped one. I did find an NOS one on eBay. It’s run fine since replacing that and restoring the saw.

I x-rayed the failed doughnut at work, thinking I would attempt to draw out the circuit someday from the x-ray pics, and dig into the potting compound to replace the failed components. I assume this one uses an SCR as the switching component. Below find pics of said trigger module, and the saw.
