If you want the repairs done correctly and the latest revisions, you need to send your engine back to us. We don't recommend having other shops work on your Quickdraw because they don't have the equipment it takes to do it correctly, that is because they don't need that equipment to work on a Zenoah.
Send your engine to us at:
