Default Re: Will moving the screw, retard timing on my 47?

The adjustment on the side is usually set with a timing fixture tool on the bench and then left alone. Points gap settings can also have an effect. Setting points to specs is usually the first thing then check the timing setting to get it all in sync. A steel rule can be used if following the procedure in the operator's manual or shop manual to check or adjust timing.

There may be something wrong with the advance flyweight unit or vacuum brake. It's best to check all that stuff for condition and smooth operation if you take the distributor off for service.
