issue with tuning holley carb/ 351c running rough
Am I wrong in thinking the choke being closed meaning I can't see the butterflies underneath? When I close that flap it dies. Carb is 3310 I belive. Screws are 1.5 out for mixture. My distributor is mechanical advance not vacuum
The choke is only mostly closed on cold start. After the engine starts the choke is moved to mostly open. As the engine gains some heat the choke is moved to the open position. If the engine is running and the choke is closed the engine will quit running due to super rich mixture. Chuck
So when warm the choke has to be all the way open? Damn I have been thinking opposite. I can't get my center gauges to work to monitor temp so I'll have to warm it up good.

Has anyone else had trouble with msd wires?
You mean My-Spark-Dissappeared wires? no but I had problems with a TFI ignition coil a while back ago. You could use a cooking thermometer and carefully check engine temp with the radiator cap off.

I had one bad set years ago. MSD sent me a new set for free. I sold them and bought a set of cut to fit Taylor wires. Chuck
I'm thinking of picking up the stock autolite originals. Just wasn't sure their quality
I have purchased two sets of "concours correct" Autolite/Motorcraft wires. While both sets worked OK, both sets proved to be fragile and hard to get off the plug without damaging the boot or the connector. Chuck
Put autolite 25 gapped at 0.05 new wired and it sounds a lot better. Still needs a bit of fine tuning
The floats are 'set' from the factory but you have to confirm on the car. It's easy to open the site bowls and see if gas comes out. Also it only take a small piece of stuff to make a needle stay open. Always check floats first if you suspect a fuel issue.
