Chains right out of the box should generally be shortened some to get a good fit . And you will see many builders do not run a tensioner , and many do . Adjusting a tensioner , to me , is an easy fix when your chain stretches after a few miles of use . Some just take another link out which is a little more of an aggressive way to take up the slack . The mix of oil to gas changes after about 3 tank fulls . A new motor uses a mix of 16 parts gas to 1 part oil . After you go through a gallon of that mix then go 20 or 25 parts gas to 1 part oil . That is using regular 2 stroke oil , not synthetic . You tube may have a demo tape on throttle installation or check the operators manual on the previous reply .
