Honda EU2000i Smoking and Unable to Power a Load

Published at : 23 Dec 2025

A subscriber from South Carolina sent us this EU2000i to take a look at. It is smoking when under load and having problems powering a load. Is it an easy fix or does the engine require a rebuild?

I no longer use Harbor Freight Super Heavy Duty Degreaser in my ultrasonic cleaner. Harbor Freight changed the recipe. The bottle previously stated "NON-CORROSIVE". Now it says "CORROSIVE", "do not user on Aluminum". It now damages most carburetors. Recently I have been using Simple Green PRO HD with good results.
