Web4 mei 2009 · Advancing the ignition timing has the effect of leaning the engine out and retarding the timing the opposite; it has a tendency to richen it. At some point, and it varies, if the timing is advanced too much this causes a subtle, or not so subtle, tendency to richen the fuel/air mix due to a performance drop off. WebRetarding the timing does the complete opposite. It lights the compressed fuel & air later (at, or after TDC) and doesn’t create enough cylinder pressure to make good power, or to create a good idle vacuum. Because the burn is lighting later and the pressure is lower, the burn happens MUCH too slow.
