Harrys31coach	Hello Bare Feet, A VCCA post by CJP'S 29 08/11/10 04:58AM #180437 states: The centrifugal advance figure for Delco-Remy distributor model 633-G are as follows: Advance starts at 700 engine rpm's with 2 degrees advance At 2,000 engine rpm's,advance is 25 degrees Maximum centrifugal advance occurs at 2,600rpm's and is 31 degrees. I'm thinking that if your static (engine off) timing of 12 degrees, automatically moves to 18 degrees running (engine on) at idle RPM, something may be amiss within the centrifugal advance mechanism. Broken,loose,weak or missing springs maybe? Let us know what your idle RPM is set at. I believe, after the static timing is set, all other timing adjustments are made with engine running.
