Honestly I cannot say more at the moment, I experienced quite a bog with secondary opening ( EDL Thunder 800AVS) evn with electric pump feeding the carb, so I need to do more test... At the moment thank you so much!
Have you adjusted the air door ? The will require some tuning .
I set the air door adjusting the screw as suggested as default setting, I must test again to see if I set it too weak or too hard to open...also I have a bad smell of unburned fuel at idling..I'm not a pro , not a mechanic, so I need time to understand what the best combination of rod -spring jet etc....
