PS if all else fails
4 hole spacer under carb
if that works then maybe....
stick this in your manifold
https://www.aussiespeedshop.com/product ... -manifold/
turns a race only manifold into something that works better on the street
i.e if you find a 4 hole spacer under the carb makes things better then this is the next step
better distribution at low RPM with only a small impact at higher RPM but obviously has an impact on WOT all out race operation in the 5000+ range where plenum size/space is king

Got a 'phenolic spacer' on (spelling?) to keep heat out but clearance is TIGHT (like 1mm tight) to bonnet. It doesnt *quite* touch but its damn close.
Thats an interesting thing. Never heard of that.

you will know when you get total advance right
it just gets quieter and smoother.... i can't explain it its not an all out power change no real seat of the pants feel as such... its a sound and feel change. it lets you worry about noises that previously were drowned out

Quick answer - no idea. If thats what Bob had, yes ! (got a pic somewhere).
EDIT - Yes, seems I am, looking at the build sheet for engine. "Rhodes Variable Duration"
Morgan, you are right that they are designed to soften a lumpy cam by bleeding down at idle, but I know that they can be problematic - either not bleeding down, or not pumping up. If you've got some and some, it could cause the symptoms you describe. A vacuum gauge is your friend - if it flutters at idle, something's not right.
Sorry if I'm repeating (or contradicting!) advice already given - I confess I haven't read the whole thread
