The M rods are gonna severely hamper performance when getting into the throttle (passing, pulling hills or WOT). Just going back to the stock config should help a bit.
If the car has a more aggressive cam, the idle circuit will need some attention.
Between the bushings, secondary cam, bent power piston rods, and wrong primary rods the carb has a lot of rreasons to run bad.
Bring it back to the stock config and repair all the faults and it should be a night and day difference.
I know Cliff would recommend going to the 70/70 setup. I believe that the fuel curve becomes more predictable with that. In stock config my 17058228 was pretty lean at light throttle and cruise, and horribly rich when the secondaries opened up. (with a pretty significant bog as they opened up to boot
)
I'd love it if Cliff(or someone else) could explain the effects the air bleeds have on the fueling curve. I think I understand most of the systems now but this is one that I'm still not 100% sure on. I understand that it's emulsion air and more bleed = leaner mixture. My question is more along the lines of "What will be different between a 70 bleed and a 125 bleed if the jets/rods have been changed to compensate?"
