Got an 81 2.6l mighty max, original carb and all. The thing idles at like 3000 rpms and when it's first started in the morning it misfires like crazy, hesitates a bunch, but goes away when it's warmed up. But the high idle starts once it's been driven a few minutes. At first it doesn't idle so high. I looked at the carb a bit but that thing is insane with all the lines... Overwhelming! When I push on the plate on the top (the barrel closest to the driver fender) the idle slows down.. Idk if it's the choke, I don't know how this crazy thing works! What can be the cause of this issue? I also get like 10 mpg at most. Can I get a different carb? A weber? Edelbrock? Etc, just something that is easy to tune and has a manual choke. Also the thing ticks like crazy like it needs valves adjusted.. Anyone know how? Truck only has 60k on it. Nice toasty brown plugs, doesn't smoke at all, so it's worth the trouble to me!

thanks in advance!
