Not Ranked
Hi Phil,
You will see on the racingfuelsystems website, that there is a thread that mentions how an engine can still idle well with a PV plug fitted and NO main jets fitted as a test.
Finally somebody has admitted that Main and PVCR does not affect idle quality.
If your metering blocks have the IFRs up high, I would moved them down to where they "should be".
