jason.perez Posted February 5, 2021 Author Report Share Posted February 5, 2021 Also forgot to ask what float height to run them at? Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted February 7, 2021 Report Share Posted February 7, 2021 The PWK will come with their own needle. Most PWK take 45-50 pilot and 155-165 main, depending on temp and elevation. Quote Link to comment Share on other sites More sharing options...
jason.perez Posted February 7, 2021 Author Report Share Posted February 7, 2021 They gave me CEL needles I think I’ll just run then middle clip for now. I put 45 pilots and 165 mains in sure there gonna be to Rich since when I jet it it’s going to be 3000 feet I stead of where I’m located at 300 ft Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted February 7, 2021 Report Share Posted February 7, 2021 Yea, Likely have to drop to a 155-150 main for that elevation. The pilot will probably be fine. Quote Link to comment Share on other sites More sharing options...
