the carbs are flooding when engine is shut down and hot
you can here it boiling and look down the bore and they are dripping from the middle winged looking thing (aux vents?) on #1&3.
Who's the IDA whiz on here? I never saw this with my IDF's....... any tips?
there are a few things that cause this.
first if your car is lowered in the frt a fair amount ,the fuel level in the float bowl will be higher at #1,3 and lower at #2,4.if combine this with a misajusted or high float level this can be the cause as well if you add a leaky needle and seat fuel will just pour out .check the float hight ,leaky needle and seats and if these are ok and it is due to a big rake then drop your float level 1mm.a good test is when you heavy break or decel down hill if your motor starts to die more than normal because of fuel dumping into #1,3 lower the float height.
you have a data loger you can map this.
myself,i run at 1.5 mm float height and for street use hook up my fuel pressure regulator to my advance vaccum port on the carbs .
also shut your electric pump off before you pull into the driveway etc and dump the pressure in the system and use some of the fuel in the lines and bowl,agan watch your data loger when your a/f ratio starts to lean out shut it down
