If you provide the information below, maybe someone can offer some suggestions:

How did you break-in the engine? Just let it goes and screw the HSN

What is your head clearance? No change, default setting

What % nitro and plug are you running? 5%

What are the HSN and LSN needle settings now? Someone helped me to tune. So It's, HSN 2 1/2 turn from close, LSN 1 turn from close.

What is your idle gap inside the carb? I saw it around 1mm and little more

Are you running the car at sea level? on the hill
