your barking up the wrong tree with your recommended fixes----seconary jet extensions are for acceration, and you already have the slosh baffles--your cure can be as simple as lowering the float levels to maybe even pushing in the clutch a micro second sooner when you come to a stop

You're correct Jerry. What they told me was that the jet extenders are normally for acceleration but on other folks who've had the same problem as I'm experiencing they've put them on the rear bowl and it corrected the problem. I went out and tested it and it didn't correct my problem so I quess I'm up in the willow tree huh The carb mfg told me that should have corrected the problem and he's going to get a couple of his folks together to see what they think my next move is. I think I'm going to give TomH440's idea a go and lower the float some.

I'll get this thing yet

You've got the extenders, why don't you just try them in the front bowl.
As I said , it worked for me.........several times.

Like all the other advice you have received, I'll reiterate the fact that jet extensions on the secondary are for fuel starvation on acceleration.
Unless your float level is too high, they have little to do with sloshing into the venturi on deceleration.
High float level and long tubes may work, but the main well would get uncovered, then a stall condition of lean return to idle may exist.

You should have bowl vent whistles fitted to both bowls, jet extensions on the secondary with a notched float, and the float levels just under the sight plug.

Thanks for your feedback on this issue. As I'm sure you can tell I didn't graduate summa cum laude in carburetor tuning If you notice from the photos I linked I have bowl vent whistles installed. The folks at AED specialize in performance tuning carburetors so I've been trying to take their advice on this. They told me that they've had folks put on rear jet extenders when they've had a problem like mine and it's fixed the problem??

I did notice yesterday when I started the car it didn't want to idle very well until the motor warmed up some. Maybe to lean

Anyway I appreciate your feedback on this. I'm probably going to try and richen it up just a little to smooth out the cold idle.
