Leaky Carbs

[crazylegs]

HI having problems with a 73 bus with stock carbs flooding itself overnight .
The fuel pump is a rotary Pieburg (max pressure 2/3psi) wired into the coil.
There already been (or so I'm told at this point ) new float valves etc been fitted to the carbs .
Thinking of redoing the carbs again with new float valves again etc and maybe wiring the pump through a relay wired to the regulator .
Anyone any more suggestions ?

Thanks

Bad floats are a definite candidate for leaks. If you need a quality rebuild, get in touch with keifernet (PM him). He's da man.

New needle valves often require positive seating, use your finger while you blow through the inlet.
Check your fuel levels very carefully, installed on the engine with the car perfectly level, they should be 13mm below the body of the carb with floats in place.

I had a flood incident a month ago. It was just crap in the needle valve. Took 30 minutes to disassemble, clean, reinstall.
