I have seen this question from several people here, I hope this finds its way to somebody it can help.
I purchased a cs-750evl and got it running. It died while cutting the first day - no spark. I read about the module issues, I saw the expensive parts on ebay.
I happened to have purchased a cs-602vl at the same time. The chassis are the same. The flywheels are the same physically, but the magnetic strips are in different places. The 602vl (no "e" means no electronic) has points. I purchased a cs-602vl flywheel, and a cs-602vl coil/points(cs-701vl & cs702vl also work). I purchased an oregon universal module, deleted the points, and wired it in. Now I have spark - used the saw on a job for some bucking and stumping. I disassembled after to make sure no new wiring was rubbing, because you have to run the wires under the flywheel (be careful removing the flywheel, easy to break - I used a steering wheel/dampener puller and two long metric bolts)
If anyone wants more info, please let me know.
