Sure its not just the condenser? That's funny that your looking for parts for your dealer.
Here's one better. A so-called tech at the Stihl dealer knew I was into the old 031s (at the time). He mentioned he picked one up and wanted to know if a 310 coil would retrofit. I told him not even close. I asked if it was a points 031 or electronic. He didn't know but said he would find out. A week or 2 goes by and I asked if he figured it out, said he hadn't found the time. I told him give it to me and I'll fix it for you. No response. Next time I was in the dealer he sold me the saw for $5 even after I reiterated my offer to repair it. Took it home, intalled a Nova module and it turned into my best running 031. His boss later on asked about the Nova module and I sold him one for what I paid for it. Seriously.
Some people, you can't tell them anything.
