Our 90RRC now has a new distributor (but her timing isn't happy. Installed 6* B (as Rave instructs, vac off etc.) and then wanna strobe time her to 9*/10* B but she dies. A tooth either way doesn't help. Also tried dizzy installs starting at 10* al the way to 18* - She seems to like the 6*B best as she idles there. Don't think her timing chain is bad as the rotor moves with the slightest hand crank. Anyone have a different method? Thanks.
