pistonbroke Posted January 16, 2012 Report Share Posted January 16, 2012 Does anybody know what the mixture screw setting should be on a Gas Gas 280 TXT Pro 2006 with a Dellorto carb. Thanks Phil Quote Link to comment Share on other sites More sharing options...
chewy Posted January 16, 2012 Report Share Posted January 16, 2012 Until it runs as smooth as possible on lowest tickover..... not (in my experience) easy to arrive at with the Dellorto..... engine warm (fan come on and gone off) start at c. 2.5 turns out from full in. Lots of thing may have been changed on your bike since new ...so maybe best to verify that you have correct jets ,needles ,slide, spark plug, air filter etc..don't ask me where/how!
