Does advancing timing lean or rich. This helps prevent the engine from getting flooded with fuel, a process known as ignition advancing. Jan 29, 2009 · Richer/Advance or Lean/Retard ? Which is the better options ? To richen it and advance timing or lean the mixture and retard timing ? My thought will be, by running richer, we run lower risk than leaning the mixture ? However, enriching the mixture first causes worser fuel consumption and also introduces incomplete burn. go to bottom go to top Jul 3, 2003 · If you're rich, you can lean out the fuel pressure by way of an adjustable regulator and/or you can advance your timing. While the direct impact isn't as simple as a direct shift in AFR like adjusting a carburetor, advancing timing significantly *influences Jun 19, 2009 · What should you do to the timing, if anything? Some things, possibly misconceptions, that I've heard in the past: - Advance timing until it knocks and then back off 1-2 degrees - A the flame front in a lean mixture burns slower, so more timing advance is appropriate, (intuitively a rich mixture would need less advance) - More timing Jan 31, 2025 · Quote from ODB Eleven forum "When your car's engine detects a fuel mixture that's too rich, it adjusts the ignition timing to occur earlier. Ignition timing is an important process when it comes to running an engine. Jun 19, 2009 · What should you do to the timing, if anything?

We would like to show you a description here but the site won’t allow us. Any expert advises ? Jul 29, 2008 · Im not the most mechanically inclined I must admit, and I had a pretty simple question. Therefore, advancing the timing does not directly make the engine run lean or rich; it changes the efficiency with which the existing air and fuel mixture is consumed. Will advancing my timing make my car run more lean or rich? Home - ThumperTalk May 5, 2018 · Timing advance and running rich Jump to Latest 6. If the spark plugfires too soon or too late during the compression stroke, damage to the engine can occur over time. Conversely, if the fuel mixture is too lean, the engine will slightly delay the ignition. Apr 30, 2024 · Here are some key points to consider: Initial Timing: – The initial timing for a small block Chevy is typically set at 4 degrees BTDC (Before Top Dead Center) when the engine is started, and it advances as the engine runs.

Turning the distributor counterclockwise will advance the timing, while turning it clockwise will retard the timing. Sep 4, 2024 · The total timing at higher RPMs, such as 3000 RPM, is typically around 38 degrees. I've searched hard found nothing. The air/fuel mixture in the combustion chamber is ig Aug 28, 2025 · The relationship between ignition timing and air-fuel ratio (AFR) is a crucial aspect of internal combustion engine tuning. 7K views 28 replies 13 participants last post by novafornow May 14, 2018 J Apr 27, 2022 · This is why you have to adjust the timing right when your engine runs too rich or too lean. Understanding whether advancing timing leads to a leaner or richer condition is fundamental for optimizing performance and efficiency. A mixture with poor atomization of the fuel burns more slowly. 6. Mixture and timing are independent, but related as above. On 91 octane you'd most likely have to retard your timing. The spark plug fires during the compression stroke. 2, if I advance the timing to 18 degrees, would the air fuel get leaner or richer just by adjusting the ignition timing? And vice versa. Vacuum Advance and Mechanical Advance: – When a small-block Chevy is started, the spark is retarded to 4 degrees BTDC. Sep 14, 2021 · Examples: A mixture that is too lean burns more slowly. Adjustment Process: To adjust the timing on a Chevy 350 engine, you can rotate the distributor housing in one direction or the other. 7K views 28 replies 13 participants last post by novafornow May 14, 2018 J Jul 11, 2009 · Does it help rich and or lean carb mixtures. A good way to enhance your camshaft’s low-speed torque with increased duration is to advance your intake lobe but in relation to your exhaust. A mixture of poor quality will require more timing advance. 2. Jun 22, 2005 · DOES IGNTION TIMING AFFECT A/F RATIO??? Does retarding and advancing ignition timing on the distributor affect air/fuel ratio? Example, say ignition timing is set at 16 degrees and a/f ratio is 13. After being cut for the 9th time, I stopped using Occam's Apr 27, 2022 · This is why you have to adjust the timing right when your engine runs too rich or too lean.
