Power Valve Selection: The Definitive Answer
I've never seen an IFR in the P position. Is there a benefit to that?
There must have been, but I don't know if it was performance related or manufacturing related.
I'm pretty sure I have a block at the garage with the IFR in the well. Just haven't removed the top plug to check.
Both Mark and Tuner have mentioned the somewhat high IFR on a secondary metering plate can cause fuel in the idle well to get blown into the main well when the throttles open. It acts like a pump shot. It seems like that could also happen with a metering block that has a IFR around the same height as fuel level in the bowl.
Just guessing here.
lemme see if I was smart enough to save any photos. Apparently not. Hopefully I saved some links in a word document.
I'll have to search ST and more likely RFS forum.
Edit:
Here's the references to the meter plates - mostly on vac secondary carbs.
