That's what I thought you meant. I went back and you mentioned a kit to replace the points and condenser also. So, I wasn't sure?Joe,you can't use a chip on an electronic ignition module (mistakenly referred to as a "coil").Maybe you misunderstood my previous post?The Wico/Prestolite ignition module (commonly referred to as the "blue coil of death") was used on the SXL,XL-12,SEZ,XL-1,& I think as early as the XL-850,& the ignition module took the placer of the points & condensers.Phelon/Repco also had their version of the electronic ignition module as well.
I have used chips to replace the points & condensers on several saws & yes,they're easy to install.However,I do not use the Nova II chips as I think they're too thick & can't be used in some instances.I prefer the thinner one wire chips that sell for around $15.
So, is there away to "Fix" an electronic ignition with out finding a repro or original? If so, I wonder if I could adapt it to an Echo? I have 2 Echo 750's with bad ignitions. My cousin's SIL is an aerospace engineer. He makes tools for the Space Station. When I asked him he laughed and said, "70's technology, I could make it in 5 minutes." But, he wanted me to get him a wiring schematic, which I couldn't find?
