@ Mike eash  , glad you are on it  paying attention to its running gains / changes , often refer to that , on my experience . as your  hours , run time gain , noticed zero smoke , just very easy  function . my oil changes now always include that zinc, read all the related info on it , use a measuring cup , just a trial that really made the running difference .  anything I  refer to you , I  am currently using , so i know it works , like to make a chronic issue , a strong point , isn't that what you want ? everything I changed / improved WAS A PIA , now every one is a  solid / reliable run stage. let me know how how its going , another problem area ?  ANOTHER you can't do that , is the STA BIL , fuel storage , in all my ethanol gas , think about it , fuel filters are clean , fuel bowls are clean/ clear , years ago replaced all lines , tank valve set up , have a good one , pete
