Hello all , To introduce myself. Retired mechanic living in Connecticut. Owner of a 1985 RX7 GSL-SE and a 2005 RX8. The GSL was stolen and stripped. The RX8 runs fine and is stock. I joined the forum because of the GSL-SE. I'm trying to get that car running. The 13B motor was replaced with a maroon colored 12A motor with a Weber carb setup and a MDS 6AL ignition setup,that is wired wrong. Both ignitors were removed from the distributor. One of MSD coils is defective. I've replaced the defective coil for the leading combustion chamber, but have no way of getting spark to the trailing combustion chamber. A replacement ignitor is expensive and I need a way to get spark to the trailing chamber as cheap as possible. Can I use a setup from a GM ignition or some other manufacturer to replace the missing ignitor? The stock pickup assembly is still in place for the trailing chamber. Any suggestions? I do have spark to the leading chamber using the MSD system, using the waste spark setup. Compression is at 90 PSI all around, so I believe the apex seals are still okay. Is there anyway to identify who rebuilt or remanufactured the motor from the color and the Weber carb setup? I couldn't find any tags on the motor. Any help would be appreciated. Best Regards, Ken P.S. The RX8 is in California for the next 6 months, so I can't swap any parts from it. My son is enjoying it!
