After 3 long days of completely taking apart my savage 21 and cleaning it and putting it back together I found that the carb setting were way off. When I was trying to tune the engine the hsn was really lose and whenever I was to rev the engine, it would vibrate out of its position. I was thinking about buying a new carb because of its age but I was going to sell the car so I wouldn't want to spend the money on it. Also the fuel is back flowing. Clueless!
