To tell the truth I don't know what my mileage is. When I put new stick on numbers on the odometer, and put it in , it only worked for about 1/10 of a mile and since the new electric wiper motor and linkage block the removal of the speedo, it hasn't been touched. It just seems like I'm getting less than 15mpg.The carb has never been rebuilt and kind of oozes a little gas around the base,maybe that should be my next project
