I don’t know. I suspect it should show continuity. Hope someone on this site can give more authoritative answer. How about disconnecting the sensor and see if it starts?
Starting Trouble Honda GX-340

Google has this.
"To test a generator low oil sensor, disconnect the sensor wire harness and attempt to start the unit; if it starts, the sensor is likely faulty. Alternatively, use a multimeter to check for continuity to ground while the engine has proper oil levels; a functioning sensor should show no continuity (open circuit) when oil is full."
Thanks OddJob & Slomo.
Experimenting showed that ground to sensor is open until oil is low. When oil is low, the sensor uses the wire to short ignition to frame, killing ignition.
Today, I was able to re-test spark. It was weak. I cleaned the rust off of the magnet and the laminated arms of the ignition. I set the gap and the spark test was strong & blue.
I suppose that the rust made the gap smaller? (Guessing)
Next, I adjusted the valves' rocker clearance. Intake gap was correct. Exhaust was several thousandths too large. It runs well.
ODD-
I noticed two black areas on the foam air filter. I can't figure out where they came from. The paper filter below it is spotless. The filter has 2 hours on it. Do you guys have an idea? (Photo below)
Thank You All Again for helping. I very much appreciate your help and advice.
(Warning! I will post a separate thread about the obsolete in-tank fuel strainer. The grommet is cracked & leaking. I didn;t want to clutter this thread)
Enjoy Today!

Interesting Discovery About Coil Gap Setting:
There are 2 pair of slots in the plastic fan. One can align either pair with the laminated legs of the coil to allow a feeler gauge to slip in straight. I found that helpful.
Interesting Discovery About Adjusting Valve Rockers with this GX-340 engine:
Removing the recoil starter housing reveals a tiny triangle stamped into the hub into which the recoil fits to turn the engine over. When that triangle is facing straight up, the piston is at Top Dead Center (Compression or Exhaust) When there is no tension on the rockers, the piston is at TDC for compression & ready for valve setting. It's never knew that until I noticed the triangle and investigated.

Does it have a CO2 sensor?
Doubt it.
Thanks for asking, OutdoorPowerMike.
It doesn't have either a CO2 or low oxygen sensor as some new ones have.
