    Help - Bosch Twin Plug Distributor Cap & Rotor

    My RSR 3.0 twin plug motor has developed a significant intermittent misfire. Suspecting an ignition problem and knowing that my 10 year old Jerry Woods modified SC Bosch distributor still had the original cap and rotor, I checked there first.
    The inside of the cap shows what looks to be oxidized copper (green dust). The contacts on both the cap and rotor show significant corrosion. I expect this is the cause of the misfire.

    The original Bosh twin plug caps and rotors are very costly. Anyone have experience with the reproductions that are now available and know where to get one?

    Not sure it’s the same, but check with Aaron burnham...he helped me when I was in a similar bind a couple of years ago, on my 72 twin plug setup. http://www.burnhamperformance.com

    Talked with Aaron and Henry Schmidt today. They recommended the repro cap and rotor available on EBay. I ordered one.
