Post Paint Startup - Carb and Trans woes

Well, the car came back from the painter a couple of weeks ago, and I have been hard at work putting it back together. I finally started it up today. This is the first time that it has run since a short go cart ride after the cam break in. I ran into a couple of issues..

1) If I depress the accelerator, the throttle gets tuck at about 1/8 stroke. There is a spring mechanism at the back of the carb that seems to be locking it here. It runs up to 3000 rpm (rev limit for now) and hangs there. I have to shut it down and push the throttle back to get it to kick down again.

2) The idle is hanging out at aroung 500 RPM, which is right about die zone.

I do not remember either of these two being an issue before. I have put the base plate for the Oval Cobra air filter on, and this is holding the choke open, which I am fine with becuase I was just going to wire the choke open. This is the only change since the last go cart ride.

BTW, this is a 302 engine with a Holley 1850s carb (600cfm). I plan on going out to get the Haynes Holley performance tuning book, but would love any suggestions in the mean time. I have a rush going and would love to go our for another gocart ride.

3) The trans does not want to stay in second. After noticing this, I did some playing. It is fine in first. If I put it in second with the car not running, I can lightly tap it and it comes out of second, and if I rock the car, it pops out. Not running, all gears stay engaged when rocking the car except 2nd. I am using an after market shifter, but have the stops removed. Any ideas? I do not know the brand, I think it is a Pro 5.0, but not positive, I bought it off of someone on the forum. I would appreciate any ideas on this one. The big problem is that on the B&B, the shifter is under a fiberglass tunnel. I cannot just remove an aluminum panel, and to put an access panel in would be a little work (although I may just make it out of aluminum if I need to.

Two things, any chance the choke set is on a bit and holding the thottle open? Check the screw on the right side to see if it is getting the link.
Second if the car did not pop out of second before and does now you may have throw problem on the shifter but it sounds more like a bad set of gears in the trans. Hope I am wrong on that one.
