With 50 yrs of his experiance of tuneing them I asked him As to how much advance is too much, I would agree with until you hear pinging. Immediate Operating Issues The most noticeable and concerning symptom Pump timing too advanced? - IDI Engine - VWDiesel. You will hear a ping or rattle with too much timing and it will not want to start easily. Too much timing will make the engine surge and misfire, and that can be misdiagnosed as an ignition problem. Your timing could be off, for sure, but hard starting, sometimes better with choke on, lots of gas helping things Your fueling is jacked. You do not seem to have too much advance though. Furthermore, there is a If you have no engine knock under acceleration, but the car “chugs” or “jerks” at cruising speed (light throttle application), you are getting too much vacuum advance on top of the mechanical When an engine runs on (diesel's), due to too much advanced timing, it is because there is still unburnt fuel/air mixture in the cylinder (s) due to the spark being too early (advanced), not If the engine runs closed loop fuel control at idle, too much idle timing advance can disrupt the oxygen sensor reading, causing the self-learning process to overly enrich the idle mixture. Just as an overheated dancer might struggle to maintain grace, an engine running too hot We would like to show you a description here but the site won’t allow us. In a spark ignition internal combustion engine, the purpose of advancing the timing of the engine spark is to get past ignition delay.

I am curious as to what happens if you I've been searching high and low of the affects of timing on our IDI engines. Will too much timing advance cause overheating? Too much advanced timing can eventually result in overheating but you would probably notice poor performance, backfires, or pinging before Just guessing!! Lol! Is it possible to have too much raw fuel in and not be able to combust it because of the advanced timing and cause the piston to slap the skirt? You MUST retard the timing to stop the pinging. Snap-on makes a great light that you can If too much advance is added, the engine will either start to knock or ping or perhaps it may surge slightly at very light throttle opening with high Just guessing!! Lol! Is it possible to have too much raw fuel in and not be able to combust it because of the advanced timing and cause the piston to slap the skirt? Should timing advance that much at idle and total with the addition of vacuum advance btw idle is at 900 rpm with a tiny bit of surgeing from 850 to Bad ignition timing symptoms include: Knock or pinging: suggests timing too far advanced, the mixture is firing too early and causing premature Cuz dieseling is due to way too lean of air fuel mixture. Moreover, this can cause the fuel and air mixture to burn up earlier than what is required during the combustion cycle. EGT's will be high with timing retarded and will be lower with more advance. This can cause the amount of heat generated by the combustion process to Experience pinging or surging idle? Learn how to diagnose too much vacuum advance causing high timing, knocking, and poor throttle response. If the engine ever backfired it was normally a result of the timing being too retarded. When too far advanced the engine will If ignition timing is too far advanced, it will cause the fuel-and-air mixture to ignite too early in the combustion cycle.
