Hey everyone,I'm have problems with my 6 pack carbs.To start I'm running a 340 with around 18 degree timing full advanced is unknown.As you may know the 6 pack intake is a high rise so heat transfer shouldn't be too bad but when I run the car to normal temps and shut it off the carbs will drop fuel level in 3 hours down about 3/4" or so and it all seems to go in the motor as it will not restart after sitting over night unless I use a starting spray which I have been useing carb cleaner and it still won't start easy,I usaully have to recharge the battery to get it to start from cranking way too much.However after sitting over night without running the it only dropped about 1/8" from the bottom of the site screw hole.So it seems to seep or evaporate some.
Ok heres the deal after running to temp the intake just below the front carb mount reads 165 deg and the front carb bowl lower section reads 90 deg.The other intake readings were close to the around 150 deg and all carbs read the same.Also I have a plasticish "type" base gasket to slow heat transfer.
These are the OEM carbs with OEM fuel lines except for a couple inch section from the machenical fuel pump to the carb line at the pump.These are based off the holly 2300 carbs.One with a metering block and the outter carbs have metering plates.
OEM lines from the tank forward,nothing closer than 3" to the exhaust.
Float level is just under site screw hole.
As for seeping,its not dripping from the barrels above the flaps as the barrels are dry all night.So the only place I can tell is through the mixture outlets below the flaps which shouldn't have any fuel sitting on them to seep out.Where else can it go through to get to the engine?
As for the boiling,I would assume a small amount could be pushed over the oever flows but nothing comes out of the top hole to the outside of the carb.Can the fuel really boil at the temp?Doesn't seem like it should.
I may have missed something here so ask away.So such a long post but this has been driving me crazy.Thanks in advance.
