In preparing for next hurricane season, we replaced several almost new EM7000is/EM7000isa carburetors.
All generators have about 50 to 100 hours on the LCD panel but had previously sat in storage and had questionable condition of jets and passages so new carburetors went into each one and now they start and run steady in normal and ECO mode. Have plugged each into 240v transfer switches and they run easily over 36,000 (3 ton) heatpumps using only 2,400 watts of power. Tested also each 120v outlet with various compressors and pumps, no problems. All handled surges over 5,000 watts with no issues.
One question remains: All Em7000's run in normal mode (non-ECO) at about 3,350-3,400 rpm and in ECO mode about 2,300-2,400 rpm. I thought/assumed that 3,600 rpm is normal in non-ECO mode.
Can this speed be adjusted ?
How ?
