You can just throw money at it. For $70 4secondsflat.com will set up a distributor to any curve you want on the advance machine. Don, used to be very reasonable and fast return. Not to mention dead on accurate. Have not contacted them in over 10 years, but the site is still up.
There used to be tons of distributor shops that put the dizzy on the spin and suck machine. Now a days they are harder to find. Damn computers ruined everything except adult entertainment.
