Electronic Distributors From Rick Ehrenberg
I think my engine is running very lean, have a 318, Keith Black 167 pistons, 30 0ver,, comp cam 20-223-3 cam, auto trans. have a Edelbrock Street Performer intake, Holley Street Warrior 600 4160 electric choke carb., compression is 150-155 in cylinders, carb is new, shows in specs primary metering jet 66, pump discharge nozzle 0.031, primary power valve 65. have photo of plugs, running NGK gr4gp, sorry for photo quality could not get camera to get a clearer photo, center is pure white, electrode shows flaking, now has 2 black bands [ had old Holley in, and now installed new Holley unit] have about 20 miles on car with the new Holley.
Before all of my ignition problems started, with the old Holley had the plugs a very nice light tan which is the way I understand is very good. With the new Rick Ehrenberg system, this is the way the plugs look very white, and light flaking on them, which from what I can tell is on the lean side.
Do I need to richen up the carb. now? or is timing not correct? Have base at 10, and all in at 34@3000 rpm.
