i must be dong something wrng cause mine will flood up and down hills and on my side . i even had them tuned by a pro and het set it all up.. dont know whats going on then.... owell there for sale and im looking for a fuel injection set up ill trade
are you running a pressure regulator?
is your float set too high?
is the float needle leaking?
was this a new weber 32/36?
something's screwed up and your pro should be able to figure it out.
if the carb is tilted so the float chamber is much higher than the venturies, fuel will start leaking into the bores.
that can be limited by adjusting float height and drop.
by mounting bowl to firewall it should only happen on down runs(and shouldn't be too bad).
i've been happy w/mine and it runs fine from sea level to over 8800 ft(crossed forestdale divide).
start bugging your pro to straighten it out?
