YES! WE REFRESH ANY MARK SULLENS E85 CARBURETOR

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.


You will need to submit a customer engine spec sheet when ordered.  Spec sheet is at the bottom of the page.

how to Pack and ship a carburetor

Packing and Shipping a Carburetor:


***Please read before packing and shipping***


A carburetor is a precision component. How it is packed matters. If you have a carburetor-specific shipping box, use it. These boxes are designed to support the carburetor properly and prevent movement during transit. You must use a sturdy regular box and pack the carburetor correctly.


  1. Drain all fuel completely and allow the carburetor to air out.
  2. Wrap the entire carburetor tightly in plastic wrap.
    This protects against moisture and keeps small components from getting in your carburetor.
  3. Put a solid base of cardboard in the bottom of the box, put the wrapped carburetor on top of the base. Build a tight cardboard cradle all around the carburetor. Double support the corners and the ends. Cardboard should support the carburetor on all sides.  Take brown package paper or newspaper and pack in tight all around the carburetor.  Make sure there are no holes or any part of the carburetor that might push thru the box. There should be zero movement inside the box.


If the box rattles when shaken, it's not packed correctly.


Do not use:

  • Foam of any kind
  • Packing peanuts
  • Spray foam
  • Shredded paper

These materials break apart, migrate into the carburetor, and cause contamination. 

This is a hard NO. :-)


Inside the box, include:

  • Spec Sheet and payment if paying by check.
  • If paying electronically, then please use our "purchase now" feature on the custom build page
  • Use a trackable shipping service
  • Insurance is strongly recommended (Damage caused by improper packaging is usually not covered  by the shipping company.)


Please do not rely on memory or past builds. Do not assume we “already know.”  Please ask for our new shipping address. 

Each carburetor is treated as its own build. Carburetors received without a completed spec sheet may be delayed until the required information is provided.

Final Reminder
Spec sheet/ payment in the box. Carburetor wrapped in plastic wrap. Cardboard and proper supplies. No movement. No bubble wrap.
No foam.

If your combo changed, your spec sheet needs to change too.
