Solution ok  but takes too many pulls to start .  

Answer
 Hello John:

 There are 4 Possible Causes. 1- Fuel Filter Needs to be Changed. 2- The Carburetor is Out of Adjustment. 3- The Carburetor needs to be Cleaned and Rebuilt. 4- The Exhaust Port or Muffler and Spark Arrestor Screen is Blocked with Carbon. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully

 John
