Convert to replaceable idle air bleeds?

DrCharles said

Interesting. Why would the PVCR have any effect at idle, since that circuit is not drawing fuel (through the boosters)?

My idle vac is 7-8" but cruise is around 15. So I'll start with an 8.5 PV for now.

Yes there is enough metal there to do replaceable brass.

I get mine from McMaster-Carr and if you are going to go all the way (I do) you'll need 6/32, 8/32 and 10/32 brass set screws 3/16 long.

The 6/32 is for the emulsion holes, IFR and maybe one orther, the 8/32 in the PVCR and T slot restricters and the 10/32 will be your idle air and main air bleeds.

I say go for it. You'll need a small drill set, and you should have some pin gauges wouldn't hurt and a tap set.

I'm down for you working this through!!!!
