71 Berlina 74 GTV 17 Giulia Q4
In searching for information I've come across issues with motronic pistons breaking ring lands from several different and unrelated sources. In addition I've also found there appears to be an issue with certain timing lights giving inaccurate timing with MSD units specifically with digital dial back lights and some other traditional lights. I have motronic pistons and a msd and have noticed that when I set my timing to an INDICATED 33 or more degrees I have a high frequency vibration tied to rpm s best felt in the gear lever. I can retard the timing to an indicated 32 -30 degrees and the vibration goes away and the motor still runs like stink according to my redneck dyno. It also revs to 7200 with more gusto when set to the lower indicated numbers. I was wondering if anyone else has experienced anything similar? Comments, suggestions? Much gras!
