We're gettin there. We'll assume (for now) the new box is good & we know the plugs/wires are new. You might wire the choke partly open or block the rods up (eddy/carter) to see if that partial enrichment straightens it out. timing in the ballpark? but some of it don't sound like timing but might as well elim it. with RP, with the magnet lined up with the tooth you would want the rotor to be pretty close to vertically plumb inline with the bulge in the dist cap for where the rotor is at tho the symptoms ain't exactly matching that either. when we get it it is gonna be something simple!
