Did you resolve the loading issue with this G3406? If not, what is the serial number so that we can determine how the engine is built. I may be able to furnish additional information to you to resolve the issue, if you haven't fixed the engine yet?

have a new, 6 months old, 3406 Natural Gas engine that stalls under load. (located in Vietnam)
runs OK @1800RPM without load of a gas compressor.
Cat technicians already replaced ALL Spark-plugs and 2 coil-packs
swapped carburator from another engine, still same thing.....
They checked gas pressure and is withing specs, gas differential pressure @ 1.5kPa.
increased the RPM to 1860.
checked cylinder compression, produced 1585kPa.
When load goes up the engine stalls. to us it seems we having a timing/firing issue. (wire break or lose wire or short in wire-harness.)
Please need some help
