Hey all. Im having a hell of a time tuning my Amazon, and I have no idea why. B20F with dual SU HS6s. Fully rebuilt engine, fully rebuilt carbs. New plugs, wires, distributor cap, rotor, coil, pertronix pointless ignition. Seems like no matter how I tune the engine, it keeps fouling the spark plugs. Even if the carbs are leaned out to the point where the engine backfires like crazy upon acceleration, the plugs still become sooty within 5 minutes of driving. Car idles pretty rough too. Plugs are Bosch, and gapped to .035". Distributor has no vacuum advance, and has the centrifugal mechanism. Valve lash issue? Wrong temp plugs? Seems like the only way to make the engine run is to advance the hell out of it (the #1 wire output on the distributor cap is closest to the engine block) Any advice helps.
