my 86 samuria dies and wont run well enuff to get back to the house after it goes over aspeed bump. i had this problem a couple years ago and solved by swapping webbers. anyone got any ideas on what my carbs doing

Probably got crap in the carb and when you hit the bump it stirs it up and it partially clogs the jets.
Could also be crap in the tank and when you hit the bump it stirs it up and it partially clogs up the fuel system somewhere.
Or it could be something electrical related and when you hit the bump it jiggles it loose just enough that it makes the engine run crappy.
But my money would be on crap in the fuel somewhere.

well i seam to have fixed it . i took the 2 drain plug out of the carb bowl and blew mineral spirits though it to clean the bowel. the problem was still there, so i took compressed air and blew every vent port i could find.after a couple hours and many attempts something must have came loose it seems fine now. thanks for the help

Maybe a stuck float is the issue and you broke it loose?
