In the last two weeks I've done many things, but in the meantime the current problem is this definitely getting spark to the spark plug after spraying carburetor cleaner into the intake while turning the key. The only thing that happens is backfire through the carburetor or popping the engine refuses to start. The only thing I can think of is the spark plug is definitely working, so I'm wondering if there's some kill switch that allows for the flywheel to rotate where it seems everything will start and engage flywheel and the engine. But at the very last second a kill switch shuts off everything and prevents it from starting. So in other words, I'm looking at carburetor problem but maybe I should be looking for some kill switch that's shorting out everything. It's as if all systems are go but at the last second this kill switch is preventing the engine from starting I wonder if anyone is familiar with this situation before. Also, the fuel solenoid definitely clicks when you turn the key but the carburetor cleaner going into the intake. Even if there's a kill switch situation on going, I would think the engine would start up for a couple seconds. I don't think a kill switch, even if active could prevent the engine from starting for at least a second or two, but that's what it seems like is happening.
