Mopar Performance DIST with vac advance?

I believe you use a 3/32 allen wrench.Inserted thru the can port.I may get this backwards,, clockwise less, counter clockwise more.Usually I drive it first,if it doesn't ping under part throttle(Like pulling a long hill)good.If it does go about 2 turns at a time till it goes away.I think if you do a search you will find more info.
