Weber carb quirk \ Transmission slip

Looking to get some insight on two problems i am having. My first thing is a slight quirk i have with my Weber 38/38 (nuttered of course) carb. It runs "perfect" at every condition except on decel from high speeds like the highway. The carb runs little rough for a little bit at idle, once you come off idle though there is no stumble or performance issues. I figured out that it is running lean because i covered the top of the carb with something or manually engage the choke and it started to smooth out immediately. This is with the slightly larger 55 idle jet, any ideas? Would switching to manifold vac help?

Checked the vacuum gauge i get a constant 22 inches at idle, hit accelerator drops down to 5 inches and comes back up normally to 22 inches. Needle bounces VERY slighly about a 1/2 inch or so of vacuum, but i think that is normal.

Second thing i am having a transmission slip issue, but it only happens when starting the vehicle on a drive after a few days of not driving it. For example i have not drove it in the past week till yesterday and i could not even slowly let out the clutch without it wanting to nearly stall out. It will want to buck or going from gear to gear it will engage roughly. After you drive it for about 10 minutes its completely smooth, as if there is something on the flywheel/pressure plate that is being burned or worn off. Makes me think something is leaking so i added an dye to the oil. No engine leaks. Smelled the "fluid" that is on the back of the oil pan and it does not smell like gear oil. The only other thing i could think of is coolant, but it does not appear to be loosing coolant.

Advice and ideas are welcome.
