Is the throttle shaft loose?....good luck gettin it tuned if it is...I looked at a BUNCH of em before I found a good core....if it isn't loose, try the $1.98 tune up. ...bring it up to about 2500 rpm and close the choke, till it almost dies, then open it back up....this will clear most any crud out of passages that may be clogged....(Super high vaccuum)...has worked wonders many times after a carb rebuild....also make sure the accelerator pump/ metering rod setting is correct. Also float level, of course. O.G.
84 D150 440/727 79 /6 swb D150 1964 A100 window van. Just because it has spark plug tubes doesn't mean it's a Hemi.
If ya haven't been there, ya just wouldn't understand.
