Hello all. Just wanted to share the fix to a common issue that comes with new carbuteted equipment. My Honda eu2000i since day one has had a little "hiccup" here and there every few seconds when ran on economy mode which idles the generator at the lowest speed necessary when inverter loads are low. Hearing these little nuances is what I have learned in the years of me turning wrenches and tuning machines by ear, throttle response and feel. Finally I had enough of this little minor irritation and fixed it exactly how I fix any other machines..... remove the casting tangs on the carburetor and anti tamper cap on the air fuel mixture screw. You have to be careful because manufactures make these screws so that they break if ever tampered with therefore causing the mandatory purchase of new carburetors. I call it removing the emission settings. The fuel screw was 3/4 turn out factory, when it finally cleaned up and ran smooth and stopped hiccuping was at 4 turns..... I hope this helps anyone that may have this issue. I do this modification to any of my carburetor machines and they always last thousands of hours. This allows makes the engine run much cooler, which is easier on the engine and oil.
