so, when you are braking it is closign the throttle too much. hold the brake closed and adjust the idle screw to a 1mm gap. then set the throttle trim so it is the same sized gap at neutral.

Not sure how the GT2 clutch works but it could be the clutch bearings or the clutch could be holding up.

Check your throttle linkage. When the Tx is at neutral the carb should be closed. If you start applying brake and the carb goes closed more, you need to adjust the linkage. This is what the spring is for between the carb and the adjustment collar. Move the collar slightly until the carb is fully closed at neutral. You can do this adjustment with out the engine running. Then you can set your idle gap, adjust the idle mix, and start tuning. I've seen several people have their vehicles sitting there idling away, and then push on the brakes...and Unnnkkk. Engine dies. So check this also.

yeah sometimes the springs get stretched and go soft.

set the idle screw, if it idles sitting on the ground fine, then you hit the brakes and it quits, you have an idle screw problem. turn it out a little at a time till you can hit the brakes with out moving the carb back in. you can do this with the engine not running. if the clutch is bad the engine would quit as soon as the rear wheels touch the ground.
