Accelerator pump system in the carburetor is it working?

yeah it squirts like a water pistol as soon as you crack the throttle, it is perfect right through the rev range, accept right at the start. not sure if it is flooding?

I don't want to start a fire storm so you will need to do your own research on modifications to your acceleration pump system. There are a number of ways to go. What I found was that the squirt was too big and poorly adjusted and was covering up some other jetting issues.

Good luck!

so it wasnt any thing to do with my carby (hours and hours wasted) it was my de comp cable , it was to tight and when i turned my bars it was pulling on the de comp and stalling it , so if anyone has any un explainable stalling i suggest to try that. cheers and thanks for the advice
