Doesn't really matter where the poppet valve sits just so long as it seal up.Where are the wires for the kill switch? One should come from the coil pack and the other one should have been bolted to the cooling cowl.Not that it really matters if the wires aren't there but the carby could very easily fill up with dirt and then get thrown into the engine.I guess for safety reason it should also have it on and working properly.
