OK so the truck does run much better around town and does a noticable bit better on the highway but something still isnt right. It has a substantial amount more torque in first and second gear. 3rd gear and od, it is still noticable, but not as much. I'm guessing that is normal for an engine thats not known to have much power to begin with. lol

My major issue is idle. I cannot properly tune this carb because I have to run in the throttle stop 3-4 turns for it to idle at the correct rpm. The chinese clone that was on it before idled much better. I was able to get the idle right pretty quick following the guide from redline weber.
Following redline weber guide to initial tuning says I shouldnt have to screw it in (throttle stop) more than 1 1/2, to 2 turns in once the screw touches the linkage, or there are other issues. It doesnt matter where I put the idle mixture screw, it wont stay running without it screwed in a full 2 turns, and doesnt idle at the correct rpm unless its in 3+ turns.

Something else worth noting. I can run the idle mixture screw all the way to bottom out (or spring bind, not sure which is happening first) and the rpm will increase a tiny bit and smooth out a bit. I know this should not be happening. I've got it about 1 1/2 turns out right now. I would much rather have it running a little rich, than lean.
Also,a few days before I swapped the carbs, I used my timing light to correctly set the base timing at 7* btdc. That seemed to help a bit even on the clone.

Im seriously wondering if this is a rebuilt weber. It came in a bland cardboard box wrapped in a plastic bag with no other accessories or paperwork.
