Onan 4000 generator cranks but won't start

OP says he's getting spark. It's carbureted, so we know it's getting air. He tried starting fluid. All that's left is compression and timing. Check the compression ($15.00 tool). If you have 80+ psi then you are okay. Move on to timing problems. If you have less than 80psi, you have a huge problem.
Of course, he could have a faulty oil pressure sensor that won't allow it to start.
