We can't help with specifics without knowing what engine you're talking about. Generac has made a lot of differrent generators over the years so saying just the brand name doesn't tell us much.

My "go to" is first fuel; clean gas and a clean, properly adjusted carburetor. I assume the generator sat for a long time with gas in it. Did you clean the inside of the fuel tank? Did you clean or replace the fuel lines? When you installed a new carburetor was it adjusted so the engine ran well?

How many hours does the generator have on it? Have the valves been adjusted?
