    You have pretty much covered all the bases, so I’m almost out of suggestions. Almost, that is.
    1. Is this the super quiet model (with a fuel pump)? Could be a ruptured fuel pump diaphragm or pulse hose.
    2. Time to pull the flywheel and check the ignition system, especially the coils. If they have not been replaced, they need to be.
    3. Of course, this is assuming no catastrophic engine damage
    4. It ain’t the carburetor.
