Dellorto blues, I've reached my limit Options

[barefoot]

For several years after After I but it all back together the car's been running fine, had to clean one carb once and that worked fine. Now it's getting worse won't idle, it just dies after I let off the throttle. Runs strong at higher loads but very poor at idle & low load. I've cleaned the carbs enough that think I could do it blindfolded. I know the points dwell is OK and I haven't touched the advance. Using a heat gun i can measure header pipe temps just before muffler and one cylinder on each bank is way lower temperature than it's neighbor after holding the rpm's just above idle speed.
Think I'll pull the carbs off and do a compression check just to rule out one thing.
Can't even do a synchronize without a smooth idle.
Is there someone in our group who is Dell 40 expert so i can send carbs off to ???
I've prided myself as a competent mechanic but this has got me on the edge.

@Osnabruck914 @anderssj I purchased my first set of NIB DRLA 40s from CB Performance around 1982. I have used and still own IDF 40-19, DRLA 40s, and DRLA 45s. I think a conservative estimate of our combined experience 70 years. Unfortunately our experiences are anecdotal, not empirical evidence. I have never published a peer reviewed paper on the subject durability DRLA carburetors or the application of DRLA carburetors applied to a Type IV engine installed in a Porsche 914.

If @dr914 @autoatlanta.com could make me aware of which accredited institution conferred his P.hD. in 914 studies. I realize my BSEE from the University of Delaware is stale. I am hopeful that my application and CV might be enough to gain me admission.

Until I gain that academic credential I humbly stand in the shadow of @dr914 @autoatlanta.com and his assessment of my intellect "Carlos that was stupid, stupid to say"
