Jan I've just been through much the same grief with my phaeton. Went from two to one carb and all sorts. Finally nailed it down to plug length. I have fitted after market heads and old plugs were to short and not burning the gas. Don't know what your set up is but always taught that if misses under load then its more than likely electrics, if not then its gas. Having said that I am a newbie and would respectfully defer to the older more experienced heads here. How did the car run before you fitted carbs? If it ran fine then its probably something you've done. What have you changed?
Also whats a "douchebag"? Is that a northern hemisphere compliment?
