2.0 dual weber 40's, you guys know. trying to get a perfect balance on the carbs, pass side (using a spectrometer) reads 5 on both barrels, driver side reads 3 and 5 , if i adjust the throttle screw 5 and 7. have the idle at 900, timing and dwell are on. no more backfiring or popping, it actually sounds good. can't find a way over the last hump. is it a valve porblem?
