When you have the make, you can find the Honda ES6500 Generator Category.

What happens when you trurn off "auto-throttle"<?>.

Check gaskets / seals / piston rings as it sounds like oil contamination is fouling the plugs.

Is there a spark at the plug?
Is there good induction and fuel reaching the combustion chamber?
Is the choke, strangler or cold start working?

An engine needs compression, timing, the right amount of fuel a good spark and a decent cranking speed in order to start.

A side valve easy start engine is likely to have a low compression pressure as would an ohv engine designed to run on poor fuel. Other types of engine with low compression but a good cylinder leakage results probably has a dry or fuel-washed bore and adding a little oil into the cylinder can improve matters.

Take it to a mechanic and ask them to reset the ODC, or purchase an ODC reader that has reset capabilities.

If you run 12volts to the carb, will it run? I assume since it has no power at carb as you stated, that it has a fuel shut off at carb and will need voltage to activate magnet.

Remove ground wire from battery post. Make sure unit is off too. Remove start wire and cable from starter and both bolts. Reinstall in reverse order.

The TPMS lamp should go out when the proper air pressure in all tires is detected. Too much pressure will cause it to light also. The low threshold is somewhere in the 24-27lb range, dunno what the upper limit is, but one member at R4W had 44lbs, IIRC, and the lamp wouldn't go out until he dropped it back down. Some members run 38lbs and get away with it, but I run the recommended 32lbs and don't have any problems. Out of spec tire pressure does not cause the maintenance required lamp or the MIL to light up, see page 161 of the owner's manual. The maintenance required lamp will light up every 5000 miles as a reminder to change the engine oil, see page 136 of the manual for reset instructions.

1. Turn the ignition to "ON", with the engine off.
2. Slowly fully press and release the accelerator pedal 3 times within 5 seconds. The reset is complete when the chimes sound and the "CHANGE OIL" lamp goes out. If the lamp stays on and no chime is heard, repeat the reset procedure.
3. Turn the key to "OFF".
4. If the "CHANGE OIL" lamp comes back on when the vehicle is started, the engine oil life system has not reset. Repeat the procedure.

how do you reset what?if the engine oil is low you top it up to the bottom of the filler plug hole, just so it tries to run over ,then tilt the motor back slightly and put the filler plug back in,
