I need some help if someone would want to help me. I put a 302 out of a 79 ltd into a 82 f150. I got everything in it but the 302 had a variable venturi on it that didnt run the best so i took it off and rebuilt an old mid 70s 2bbl and put that on it. I am having a lot of problems setting the carb. I cant get it to run good at all. It is missing really bad and when you wrap up the engine it runs a lot better and runs smoother. It also smokes a lot. I dont know what to do because i thought it was getting too much gas but i tried to adjust it and it didnt help. what i dont understand it ran real good in the car. I was just wondering if anyone has any advice for me.
Thanks A lot,
Lane

Maybe a litle more info.Is the choke open or shut.There are really no adjustments except the choke and idle air.If its not running right,you have a problem,not adjustment.If the choke is open, the only things left are a stuck power valve,or,most likely,trash in the needle and seat.Also,did you use the same dizzy?

The choke is open and the carb was just rebuilt. It doesn't make hardly any difference when I adust the idle mixture. It seems like it is running really rich and the exhaust is really rich too.

It was freshly re-built? Running rich as well? Then it's a junk carb... It shouldn't run rich unless someone bored out the jet's on it...

Make sure the two idle circut screws are turned all the way in then out 2 turns. (just for the time being...)

Make sure that when the throttle is closed that the blades are open a little so it won't starve for air. 1/32" of less I believe..

Make sure that when you do get it to start, that there are no vacuum leaks!

Make sure that all of the unburnt fuel is burned out of the exhaust, let it run at 2,500 for a few minutes.

Adjust the carb when the truck is fully warmed.

Make sure the timing is correct and the plug wires are correct.

After you do all the above, don't forget to FIX THE VACUUM leak...
