i have just imported a 58 f100 with this motor(302/)in it,when i started it fuel was flowing out of the outlet on top of the carb,its been said that the float maybe stuck thus causing the float bowl to overflow which i understand but should this outlet have a hose attached and go somewhere back into the fuel system(tank)??)ive not identified the year of the motor yet but it has a sepentine belt system on it

 

sorry posted in wrong section

 

That "outlet" is the fuel bowl vent. On marine carbs, it'll have a "J" tube here to aim the over flowing fuel into the carb throats, other wise, it's just as it was originally intended to look like or function. The fuel bowl has to be vented to the atmosphere in order for the fuel to be drawn out of the bowl into the venturis, via the vacuum created by the pistons. Just as you figured, the fuel is not supposed to come out of these tubes in normal operation. The needle valve is stuck inside the bowl, or the fuel float in the bowl has a leak and has sunken to the bottom. Only other thing that can cause this is too much fuel pressure. Carbs only require 4-7 PSI fuel pressure, anything more will force the fuel float down, opening the needle valve it operates. JUst going by the valve covers and the serpentine FEAD system, it could be an 82-85 Mustang HO motor, but it can as well be any other year engine with those parts bolted on. The casting numbers on the block will give you a clue as to the vintage of the block, but only the date code found near the casting numbers will tell you the exact date it was cast. The date code is a number/letter/number combo that looks like a screwed on tag, but its cast into the block. The first number is the year of the decade it was cast, the letter is the month code (starting with "A" for January, thru "M" for December, skipping the letter "I") the last number is the day of the month it was cast/made. The decade is determined by the first letter of the casting numbers...........Starting with "C" for 1960's, "D" for 70's, "E" for 80's, "F" for 90's. There is no way to tell what vehicle it was originally installed in, unless the builder's tag is still affixed to the intake or carb. (and it's not on the carb in your picture)

 

baddad,thank you

 

When you rebuild that carb,make sure to remove the paint from the choke plate and the throat at least.You don't want paint chips pluging anything.Actually the carb shouldn't have any paint on it or in it.
