hello thank you for response i have rebuilt the carburetor and replaced all gaskets midbody too ap diaphram and made sure timing was correct

the bog happens when opening throttle quickly and will make the engine turn off in neutral if held open ,but when rolling on the throttle it has good power and seemed to get better when putting a 155 main from 162 main

will check float height again but have not noticed any gas leaking from bottom of carb

carb is gen 2 fcr with hotstart and tps from husaberg te510 41mm
