Lean pop at idle. The black limiting caps on you idle adjustment screw need to ne trimmed off so you can fully rotate them. Open up 1 full turn and you should be in the ball park. Stock carb with heads/cam I usually open 3 turns from lightly seated and adjust it until the lean pop goes away. This is assuming you have 0 intake leaks where the carb/adapter meet and or the intake/cylinder heads meet. No tuning will fix that. |

Thanks for the response I've ran it for a few hours like this is it possible I've damaged the motor |

There isn't enough load on a motor at idle to really have detrimental effects. Clear it up and enjoy your engine. |
