Now the air/fuel ratios are off, and the timing needs to be advanced to ignite the charge before it gets scavenged out of the cylinder Rolling


how does that work?

scavenging occurs at the end of the exhaust stroke and at the start of the intake stroke. scavenging should have finished well before the mixture is being ignited, otherwise your cam timing is wayyy off. Wink

surely you just need to get the mixture tuned back to where it was, and the timing will still be at a fairly ideal place?

or do you mean that with the extra scavenging, some fresh charge is getting into the exhaust, and the O2 sensor is reading lean (excess oxygen in the unburnt mixture)? but what dopes that have to do with ignition timing?
