Electronic Distributors From Rick Ehrenberg

Have been able to road test my car since getting it running with the Rick Ehrenberg system, have it set at 10 base timing and 34 at 3000, pulled plugs all of them are pure white, and the car has a foul smell while driving, I think it is running very lean. how would the timing effect the engine as far as running lean? I am using the same Holley carb I had on my engine which had all the plugs a very nice light tan color before all of this ignition problems came up. I did reset the Holley air fuel at idle screws not much of a change,[ from what they where] then did the road drive of about 30 miles.
