On all the JH's we have had and those I occasionally work on, I remove the vacuum advance unit altogether...and replace it with a block out unit from Jeff Schlemmer of Advanced Distributors...his web site is and if I remember correctly it is a very well engineered unit and still retains the micro adjust to the distributor. Odd your vacuum retard works at all...most I have seen are a source of air leak in the system and best blocked out or removed.
Jeff's unit, again, if I remember is about 45 dolalrs and well worth it, I think.
