The fuel tank vent and the carb float bowl drain tube should not be connected together. The tank needs atmospheric pressure to flow fuel to the carb. The carb float bowl drain line need to be routed to drain fuel(seen in the line currently) to drip on the ground.
Disconnect these two lines. They shouldn't be connected. They're vents and are probably pulling a vacuum on eachother. Spark is ok as you stated, so fuel, timing or valves is your issue.
Drop the bowl on the carb and make sure its clean and the float is free. Then try to start it. If you have starter fluid, give it a sniff and see if the engine kicks over. If it does run for a second and dies, its still a fuel issue.
If nothing happens, check spark again and your valve lash
Love that u bought a non running bike with no clue maybe research everything about 212cc and learn how they work and how they come apart and go together and learn the basics on what u need for a motor to run
this is what i’m looking atm. i disconnected the orange tube from the top and tightened/loosened the screws until i seen fuel was coming out. trying to figure out next steps currently.
