1993 Range Rover LWB
I adjusted the timing on my 4.2 RRC to Rave specs at idle with no issues. I'm a newbie to timing and have a question: with the vacuum line unplugged, if I increase the throttle to higher rpms, shouldn't the timing advance due to the mechanical advance in the distributor? With the vacuum line unhooked, my timing barely moved (no more than a degree or two at higher RPMs.) Is this normal? Do I have an issue with the springs/weights in my distributor?
