Bigging over bumps

[Trenron]

I have a 50cc 2 stroke on a hardtail mountain bike with a suspension front fork. Every time i hit a bumo the bike bogs down and i lose speed for a few seconds i have tried every carb adjustment possible has anyone else experienced this?

the flote in the carby is jumping up and cuting off petrol .best way to fix it is land softer/ smoother
