No Start, Not Sure What Else it Could Be!

[peak incompetence]

Hi, I recently bought a beat up Hawk 250. Not ridden very hard, just poorly modded. The battery it had was too small, so I had to kick start it to turn it on, but once on it would stay on. There was sputtering when I went full throttle at low RPMs, but otherwise, it was fine.

I was able to ride it 40 minutes to car wash, then, after a hard start, about 15 minutes back home. The next morning, I was able to start it and run it with a very high idle until it was warm enough to change the oil.

Once I changed the oil, all bets were off. Could not start it. There seemed to be no spark, so I bought this kit.

I ended up removing the wiring harness from the bike, and installing this kit except for the key and killswitch. I now have (weak, but consistent) spark.

The bike came with a Nibbi carb and an aftermarket exhaust. The carb has a 105 jet and the needle is set to the 4th notch down. The air/fuel screw is 2.5 turns out. I have fuel flow to the carb; the bowl fills up. I'm unsure if I have fuel leaving the carb, but when I use starter fluid, nothing happens. Altitude is 925ft.

I adjusted both valves to .06mm, spark plug gap to .032", and I've checked all the connections. The ignition coil has 1 ohm resistance.

One thing of note is that the old CDI was 6 pin, rounded connectors, and the new one is 5 pin, square connectors. Could this be a timing issue?

When I try to start the bike, I put it in neutral, turn off(on?) the kill switch, and press the starter. All it does is turn over. I've tried spraying starter fluid directly into the carb, to no avail.

This is my first Chinese bike, first carbureted bike, and first time I've taken over somebody else's project.

If you have any ideas for troubleshooting/tuning the Nibbi carb, I'd love to hear them because as of now, I'm at a stand still.
