Posted October 3, 201014 yr comment_332424 have a 1977 280z just rebuilt the motor and trying to get things set right. wanted to know if I need to short something out to get the base timing? Also get it running good and the idle were we want it and then I turn it off and restart it my idle jumps to 1500 to 2000 once or twice if I bump the gas hard the idle goes to where we want it. just hoping someone might be able to point me in the right way to solve it Link to comment https://www.classiczcars.com/forums/topic/37275-base-timing/ Share on other sites More sharing options...
