Cleanup turns to mess up. Need some help troubleshooting.

Rebuilding the carb sound like a zebra'ing the problem.

I spent two days trying to restart my slant after I turbocharged it because even though I pulled the distributor out, then put it back in, i had spun the fan for some reason and the timing was off when I reassembled it at my mark.

Another time was when the +,- wires on the coil fell off because I did not bolt them down. It was simple to verify by sticking a screwdriver near the end of the plug wire and crank it. Or put your finger in it and check that way. I've done that on accident several times. Obviously I did not notice initially that the wires were not on. But a quick diagnosis

Just like Rusty said, it takes 4 things, and if the timing is right, there's hopefully air going through the carb, you say there's fuel spitting down the bore, and that only leaves spark. I see no reason to rebuild the carb. If anything if the carb needs rebuilt it will run bad, but it will still start and run.
