At Mark Sullens E85 Carburetors, our work does not stop once a carburetor leaves the shop. E85 technology continues to evolve, and our research and development evolve right along with it.

Because of that, we may recommend a Refresh and update every few years to take advantage of improvements developed since your carburetor was originally built.

That being said, if your carburetor is running properly and you are satisfied with its performance, do not send it in. We do not believe in changing something that is already doing exactly what you want it to do.

Disclaimer:

 *If you purchase an MSE85 carburetor from a third party, we are happy to perform a refresh and recalibration to ensure it works correctly for your specific application. Please be aware that the carburetor may have been modified or adjusted by others and may no longer reflect our original calibration. For this reason, we strongly recommend contacting us before purchasing a used or previously owned carburetor so we can help you determine if it is the correct unit and avoid unnecessary cost or delays 

Refreshes are optional, not automatic. Our goal is performance, consistency, and reliability, not unnecessary changes.
