Larry-- The ignition systems that are on the market today for the most part are good pruducts--they all have their own ideosyncrasies. I think that most of the problem with retarding has to do with the natural tendency for the timing chain and cam as well as the distributor to "stretch/flex" as the rpm increases...I have always found that the "proper" way to set the timing is to gradually increase the rpm to an acceptable level say 5-6000 rpm and then check the timing----DO not zing the engine because if you watch the timing it will advance or retard as you are doing this and looking at it---Dont belive me hook up a timing light and try for yourself---Set/check the timing sorta in the RPM range you will be operating and you will have less problems---Comp 387
