Finnally got the motor running and sounds great... just cleand all the fuel lines and the carb bowl, etc. put it together and it fired right up!!!<br /><br />As it is idling, in the driveway, Every 3-5 seconds, it sort of makes a thud and shakes for like a 1/2 a second, then continues to run fine... <br /><br />I didn't let it run too long as fear of damage..<br /><br />Is it just cold?? I am changing the gear oil and impeller this weekend... Is there something I should be looking at while I have it apart??<br /><br />Is this normal for an old worn out two stroke??
