What kind of engine do you have? O & R or Tas P-7? O & R's seem to be everywhere. The Tas P-7 on mine is stuck. After searching daily for the last four years I finally found a Tas that will work!! I have a tracking number but no results yet. Hoping to get it by Saturday!! Hard to believe that in one week I got a seat, chain guard and engine!! Guess it's true that good things happen to those who wait!!
