Had the carburetor checked by shop (soaked, cleaned, disassembled, adjusted, etc.).
Put back on the bike (had bought and installed a used motor; ran fine, good compression, no valve noise).
Brand new NKG plug, gapped to 0.8mm.
Kicked it while on the stand. Started, sounded really good, ran for a minute or so.
Let her cool down and completed the bike.
Tried again. Nothing.
Push start. Nothing.
Tried again today. Nothing.
Checked spark. Yes.
Tried kicking and push starting with and without choke. No throttle, bit throttle, medium throttle, wide open. Nothing.
What could be wrong?
Possible I connected the fuel lines wrong?
I connected fuel to the lower of the 2 elbows on the left side of the bike/carb, the one facing forward.
The top to an overflow tube.
Bottom drain to overflow tube.
If NOT wrong: could it be that the choke slide is not seated properly?
Other suggestions what to check?
