Carburetor Question - Is this a good call?

you read my mind, thanks - I was just reading through that post right now in fact.

Reading your post and watching a few videos over some time here.. sounds like float level. This carb doesn't allow me to adjust the floats from the outside of the car - i'd have to take the bowls off and manually bend/adjust a bracket that holds them from the inside. this is sounding like my issue. I checked the idle screws and they're at 1.5 turns out from all the way in. Sounds like floats.

The turns out on the idle screws is not too important. That's just fine tuning info. Something to take note of. If there is no or little response to turning mixture screws - that's useful for analysing what's going on. Turn them in and the engine should stumble and then more and it should die when. (When throttle is at slow idle).

Fuel level - according to the the info on the Holleys wensite for that carb, there are fuel bowl sight plugs. Remove those to check the wet fuel level. If fuel pours out - float level is too high. If its dribbles out, the primary is about correct. Secondary I prefer keep a fraction under the plug in most cases.
Since your struggling with getting a steady idle, check the level with engine off.
