Too Much Vacuum Advance At Idle. likely the reason this engine has 24 degrees of timing is that idle vacuum increased with the additional timing. Make sure the vacuum advance connection is removed, and now rev the engine up to around 2,500 to 2,800 rpm. with ported advance, vacuum is applied once the throttle is opened past curb idle. at idle, the engine needs additional spark advance in order to fire that lean, diluted mixture earlier in order to. Ideally, the timing now should be somewhere around 34 to 36 degrees to total advance. this can be checked with the engine running at idle with a timing light. Some tuners prefer to add vacuum advance at curb idle on. I'm seeming to have quite a bit of trouble adjusting my timing/ idle speed. #1 · jul 23, 2008. In this case, the high initial timing was aggravated by a very quick mechanical advance curve, pumping an additional 10 degrees of timing into the engine by 3,000 rpm. This is referred to as initial timing. one problem with running too much vacuum advance (he's talking 24 degs in the vacuum can) at idle is when you hit. I pull and plug the vac advance line, set.
