Are you not having any response from your idle mixture screw?

Crashnzuk, the mixture screw doesn't seem to help the missing and loading up at idle times longer than 20 seconds. I realized that my tires were way down and I still need to confirm what my timing is at now. Here is a couple pics of my truck. The airdam is kinda hard to see, but it does go almost all of the way around. Note the little side view mirror. I've got an old aluminum sign I plan to use for the topper curve that may go 2/3 back and terminate with the rest of the bed flat covered so I can see out of the rearview mirror.

I found that my timing isn't advancing enough and my static timing was at 7-8 BTDC. When I leanind it out a 1/4 turn and changed my static timing to 10 and raised my idle just a smidge it seemed to be better. I'm going to set it to 12 static and see if I can lean it a hair more. I think it was only advancing to about 35 total. Its off of ther measured scale. I'll have to find a way to scale it out to see. I did some measuring this weekend on the camper taper. Hopefully, I'll find some time to put the scaffolding together for the roof section at least.

If you get back into the carb,make sure there is no leakage around the needle and seat seal.If the seal is breached you won't be able to maintain the float level and fuel will overflow into the venturi from the bowl vent.
Once your under load,the fuel use will kind if runaway from the ability to flood,but once you're back at idle,it will overwhelm the float.
I fought this for a week with my CRX before I figured it out.

Anything to report on this thing? Gotta know how the Dodge is getting on!
