UPDATE . In a chat with FAI they wanted to know the ignition timing I plan to run . They said normally the pickup setting will be 35btdc on carbureted 200 and 250 Chinese engines . They suggest 50btdc will result in better performance . I told them, I will make the mods they suggest . It will be extending the leading edge of the tab on the flywheel. In order for them to put in the programming ,this needs known up front . It has been tested and shipped to my china connection , once it arrives to her she will forward ship to me . Can't wait to play with it
