Moderator Airhead Posted January 5, 2014 Moderator Share Posted January 5, 2014 sounds like either you have an air leak somewhere or The throttle slide isnt closing properly Link to comment Share on other sites More sharing options...
dt502001 Posted January 5, 2014 Share Posted January 5, 2014 turn the slide around sounds like you have it in backwards Link to comment Share on other sites More sharing options...
Hitchen187 Posted January 5, 2014 Author Share Posted January 5, 2014 Do you mean by throttle slide the end of the rev cable because thats seated fully in the carb and is it possible put reed valves in upside down Link to comment Share on other sites More sharing options...
Hitchen187 Posted January 5, 2014 Author Share Posted January 5, 2014 The inlet manifold is tight on the carb could the seal between the reed valve, engine and inlet cause this problem Link to comment Share on other sites More sharing options...
Moderator Airhead Posted January 5, 2014 Moderator Share Posted January 5, 2014 the slide is inside of the carb, it's what lets air into the engine Link to comment Share on other sites More sharing options...

Hitchen187 Posted January 5, 2014 Author Share Posted January 5, 2014 Is that the block that has a spring above it that screws into carb and moves up and down when you twist throttle Link to comment Share on other sites More sharing options...
