Overview

Generac 0H9838D100 is the genuine Generac carburetor assembly for the 420cc engine used in Generac portable generators, including the XT8000E. When stale fuel leaves varnish and gum in the jets and passages, a generator can surge, run rough or refuse to start; a complete new carburetor is the quickest way to restore the correct fuel-air mixture.

Frequently asked questions

Which generators use the Generac 0H9838D100 carburetor?

It is listed for Generac 420cc portable generators, including the XT8000E. Other 420cc Generac models may use a different carburetor number, so confirm with your model and serial number.

Should I rebuild my carburetor or replace it?

A rebuild kit can fix worn gaskets or a sticking float needle, but a carburetor gummed up by old fuel is often faster and more reliable to replace with a complete assembly like this one.

Is this a genuine Generac part or aftermarket?

This is the genuine Generac part. Low-cost aftermarket carburetors are sold online using the same number, but they are not made or supplied by Generac.

Is 0H9838D100 the same as 0H9838E110?

No. They are different Generac part numbers; 0H9838E110 is listed for the RS7000E. Order the number that your generator's parts list shows.

How can I keep the new carburetor from clogging?

Use fresh fuel with a fuel stabilizer, and for long storage run the carburetor dry or drain it. Varnish from old fuel is the most common reason generator carburetors fail.

Where do I find my generator's model and serial number?

On the data label on the generator. Send us those numbers and our team will confirm the correct carburetor before you order.
