float bowls overflowing/ wont start

Share this page

Depends.
All the carbs do it suddenly?
Fuel pressure is?
Change anything just before this started happening?

Garbage in the needle/seat.
New fuel pump with WAY too high pressure.
Sunk floats.
 
If all three are leaking at the same time, it ain't no coincidence. In other words, they didn't all wear out their needles and seats at the same moment. Just my opinion.
 
Did any work get done on the float bowls? Are they possibly being pressurized because they have blocked vents? This may cause overflowing.
 
Has the car sat for some time? If so then you will have to drain the gas and clean up the carbs. The floats set may clean up enough to reuse but you might want to go ahead and replace them.
