Looking for parts for this old Jonsered 52e(?)....

[DIYQuestionguy]

Hello all. New here. I have this old Jonsered saw that runs and cuts great for about 10 mins before it dies out and then won't restart until cools down. I suspect the ignition module. Looks like this has SEM ignition module. Anyone know where/if I can find replacement? Thank you in advance.

Welcome to the site! As you likely know the SEM modules are very hard to come by. Once in a blue moon a NOS one may show up on ebay. Occasionally used ones show up as well but in any case these are generally expensive and used you're still dealing with 40+ year old electrics. However your situation sounds more like a failing coil. Generally when the module fails its over...done..dead. The SEM module and/or correct coil can be used from the 70E as well. They have different part numbers but that is just different length wires.
Another option is if you could find a 52 parts saw cheap you convert the 52E to a 52 points model. These are robust igns and are shared between many Jonsereds models.

Thank you. Appreciate the ideas.
