Frequently Asked Questions

  • Are your carburetors compliant with volare SB-2 (previously MSA-13) or Lycoming SB 582A?

    • AVStar's overhauled carburetors comply with all FAA regulations and incorporate a FAA-PMA approved brass float. As such, they are exempt from these Service Bulletins.

      The epoxy float in question is the latest in a series of float designs that are, or were, intended to acheive the robust performance of the brass float.

      AVStar's new FAA-PMA carburetors are now the only carburetor being installed on new engines manufactured by Lycoming. The same FAA-PMA brass float installed in these fuel systems is used in our overhaul process.

      Service Bulletins are advisory documents. They are NOT issued or approved by the FAA. Information contained in a Service Bulletin may or may not be incorporated entirely at the product owner's discretion.

  • What is your typical turn-a-round if I send in my unit for overhaul?

    • We are currently running a 5-7 day turn-a-round. If you need faster service please let us know and we will do our best to accommodate you needs

  • Do you overhaul Continental Fuel Injection Systems, Pressure carburetors or fuel pumps?

    • Unfortunately, AVStar does not overhaul any of these systems. AVStar overhauls all carburetors and fuel injection units for Lycoming applications. We also overhaul carburetors for Continental applications. If you need help finding a shop to do work for you please give us a call and we can assist you.
