yj bogs out as it pleases

ok so my YJ had a cracked carb and i replaced it with a Weber 34/34

the jeep seemed to run pretty rough after the new carb was installed still so I adjusted the timing, changed the plugs, wires, distrib cap, put in an inline fuel pressure regulator and set it at 3.5 psi, new fuel filter, and a new exhaust without a cat just straight pipe to muffler. Also, all the emmissions and such are nixed.

the jeep is a little hard to start usually crank it a few times stop then start again and with a little gas it'll start up and it idles around 1600 and then as it warms up drops down between 700 to 900 rpm's. It drives ok in first and second but if you go into third and get over like 2200 rpm's it starts to bog out and die. It is extremely tough to make it up hills and I have to downshift to second or even first sometimes to slowly try and get up the whole thing. On flat ground it runs better but still seems to slowly bog out if you really get on it and open up the throttle more than half way in third or higher.

this is my daily driver and I cant have it barely running I have tried and tried to get it to work right but I am out of idea's please help!
