i have adjusted the secondary and its operating relatively well i did have to adjust my float slightly, this morning i wend back down to a 135 main jet and a 180 air correction jet, exactly the same performance as when i has a 145 main jet and a 190 air correction jet, so i think now i either need to go one up , one down or stay the same for a main jet and it will be about as good as it will get. its running very smoothly it just feels like its lacking in power.
