well said , the important thing to remeber is when you get lost in your tune just reset the needle to flush and start over once the engine is warmed up i always check my lsp just bu pinching the fuel tube this engine idles up 3-4 sec dies and this will put you in the ball park area has been working a trear for me ,. i do this at the start of every event after i have warmed up the engine i usuall try and pput 3-4 tank through it drivibg it around
