Honda EU3000is will not start
Starting a new post. Bought a used 3000is, was told it has been sitting for 1yrs. Things that I did to it: *Carb rebuilt *Fresh new gas *New spar plug *Fresh oil (FILL TO MAX & OVERFLOWED) ...

I still think you will find that the ICM ignition module is the problem. Diagram shows that there are two ways to kill the spark--by the ignition key switch grounding the spark, or the yellow wire from the low oil device grounding the spark. Both cause the coil black wire to go to O ohms stopping the engine.
The diagram also shows that if you disconnect the ignition coil's primary side black wire (at the coil), it will completely isolate the ignition coil from the rest of the circuit... including the ICM.
If the ignition coil is fully functioning, properly installed and the spark plug is equally functional, HV spark will be produced whenever the ignition coil's black wire is disconnected... and the flywheel is spun fast enough.
This does NOT imply that the engine will run, it does however, validate the functionality of the ignition system.
